LAR, Leukocyte common antigen related, Receptor-type tyrosine-protein phosphatase F (PTPRF)

PDB-1LAR Associated subunits RPTPs (receptor protein tyr. phos.) that acts as a protein-tyrosine phosphatase Domain 1The human LAR (PTPRF) gene has 2 tandemly repeated PTPase associated tandem subunit domains, locus: 1p34.2 [§§;^] and represents a receptor-type PTP (EC 3.1.3.48), through cell-cell or cell-matrix interactions processed into 2 noncovalently associated subunits RPTPs that acts as a protein-tyrosine phosphatase associate with Trk protein tyrosine kinase (PTK) receptors in the cytoplasmic segment for dephosphorylation of tyrosine-phosphorylated insulin receptor phosphorylated by insulin stimulation. LAR is a member of the PPFIA1 (liprin) family shown to interact with PTPRF.  PTP-LAR functional cell adhesion molecule (CAMs) domain 1 (cadherin and the cytoplasmic catenins) negatively regulates dephosphorylation in part of a complex (a region of the receptor-linked PTPases, absolutely required for LCA and LAR) of proteins (Trio/DAPK)placement of tyrosine phosphorylated 1LAR that is other wise in the center between the two domains D1 and D2 here on the D1 ribbon that constitute adherens junctions (AJs), the generally inactive (D2) extracellular cytoplasmic domain two  only decreases insulin receptor mediated autophosphorylation, a process called transcytosis. The PTPRF and CD45 molecule have both domains in the cytoplasmic segment. Trio (triple functional domain (PTPRF interacting)) contains three enzyme domains: 2 that forms a complex with the cytoplasmic segments of LAR protein and a cell adhesion-like ectodomain. LAR (PTPRF) is widely expressed in receptor-type protein-tyrosine-phosphatases as a regulator of insulin receptor (IR). Liprin localize LAR to cell focal adhesions-like ectodomain, the laminin-nidogen complex is a ligand for a coiled-coil LAR-interacting protein where PPFIA1 co-localizes. LAR is important for dendrite development.

CD82 molecule, KAI1, Metastasis suppressor Kangai-1
PDB Structure KAI1 was modeled based on crystal structure of the extracellular domain of tetraspanin protein member, CD81 1G8Q
KAI1 cell-surface glycoprotein and the molecular mechanisms underlying the TIP60 coactivator complexes for the metastasis suppressor gene NGF reverts by the expression of the, KAI1: for 'kang ai' ( Chinese for anticancer) locus: 11p11.2; [§§] is a members of the Transmembrane 4 superfamily (TM4SF), are likely to be a selective downregulation strategy for many genes it is an 'activation antigen' of T cells at the level of transcription or posttranscription is down-regulated in the progression of common solid epithelial tumors that leads to the down-regulation of the KAI1 gene. KAI1 is the human homolog of the mouse leukocyte surface antigen R2. DARC is essential for the function of CD82 antigen KAI1, CD82 specifically suppresses tumor metastasis of antigen R2, CD82 (KIA), is incorporated into the viral envelope, gp78 [AMFR-autocrine motility factor receptor] associates with KAI1 (also known as CD82) involved in ER-associated (endoplasmic reticulum) degradation (ERAD), calnexin (CANX) may play a role in this process. Notch1 can trans-activate an APP target gene, Kai1, and vice versa. Tetraspanin-enriched microdomains is important for KAI1/CD82's motility-inhibitory activity are glycoproteins of unknown function, and is directly associated with the EGF receptor (EGFR). KAI1 was modeled based on crystal structure of the extracellular domain of tetraspanin protein member, CD81 and two other tetraspans, CD9-(MRP-1) and CD19. DARC - Duffy blood group, chemokine receptor (Homo sapiens) is essential for the function of CD82, early B cell marker CD9 a molecular partner (CD9P-1) and CD151 (Raph blood group) was found to be coupled. CD151 and CO-029 (TSPAN8 tetraspanin 8) are supposed to promote metastasis formation. KISS1 triggers dormancy in solitary, metastatic tumor cells. COOH-terminal interacting tetraspanin (KITENIN)-vang-like 1 (van gogh, Drosophila) by interacting with KAI1 participates in the regulation of the tumor formation as well as increased invasiveness and cells. Adhesion forces laterally organize cellular membranes via the presence vs absence of, inversely associated univariate and multivariate, Laminin (LN)- or (FN) fibronectin, associations that usually occur in the context of "tetraspanin web"; its mechanism of action has not yet been fully elucidated.

A coherent but tentative scheme actin cytoskeletal organization and cell spreading in Vinculin

Both human and chicken embryo sequences of vinculin OMIM 193065, locus 10q22.1-q23: [§§]; play a role in neutrophil migration that Viscum album agglutinin-I (VAA-I) a plant lectin possesses VAA-I, needs to be internalized to mediate apoptosis and are ingested by dendritic cells by preventing the loss of the antiapoptotic Mcl-1 protein (MCL mantle cell lymphoma) its activity is not dependent on a cell surface receptor-mediated pathway punctate foci at the substratum-facing side of the cells. A coherent but tentative scheme is proposed at the different types of contact sites. Neutrophils represent an important source of autoantigens cytoplasmic antibody associated expressed on the cell surfaces the antibody is thus most likely an anti-idiotypic antibody. Its autoinhibited head (Vh three* non-contiguous vinculin-binding sites (VBS)) and tail (Vt) domain must be activated to bind talin and actin stress fiber and formation of focal adhesions (FAs) at the cell surface but not FA kinase and vinculin an intracellular actin-binding protein apparent on isolated ventral plasma membranes in the submembrane cortex with genistein that cortical actin regulates does not depend on the ability of vinculin to associate with actin. Vinculin is required for the recruitment of talin to the immunological synapse (IS), may be implicated in the permeability barrier property of the (spinal cord, nerve fibers) perineurium. Extends into the M line showed the phosphorylation analogous to sodium orthovandate and hydrogen peroxide increased intracellular phosphotyrosine levels to that of alpha-actinin in the Z-line site found to induce apoptosis in different immune cells that extend from the M line to the Z lines that synemin may anchor IFs (intermediate filament (IF) protein) to myofibrillar Z-lines are the equivalent of the in vivo intercalated discs analogous to the transitory polygonal configurations at the (IFs) leading edge. The effects of cyclochlorotine (CC), a secondary metabolite of Penicillium islandicum damage was dose-dependently reversible to induce apoptosis. These proteins induce a rapid transition to an intermediate state of adhesiveness that includes loss of vinculin and alpha-actinin in responding to injury at the tip of the leading edge, but not of talin regulated matricellular proteins and, tenascin-C, at sites of inflammation binding to lymph node high endothelial venules (HEV) but differs from human tonsil stromal cells or neurofilament for laminin mechanisms expression. Is a new kind of adhering junctionsª (AJ) ("complexus adhaerens") scattered along the entire lateral plasma membrane of rat and human intestinal epithelium, which occur in the normal gland which is localized at cadherin-based cell-cell adherens junctions formed at the tips of thin cellular protrusions radiating from adjacent cells in nonepithelial cells localized at (ZA) zonula adherens in epithelial cells.the basolateral surface of gastric, intestinal, and gallbladder epithelia At the tip of the leading edge which is phosphorylated of the F-actin by ILK increased proliferation and migration on laminin (integrin-linked kinase-binding protein in satellite cells) and affixin in vitro.high-affinity FGFR binding sites may be formed and incorporated by the neighboring Biomaterial domain library into hemidesmosome-like adhesions cross-link on the "opposite sides" of the module. Will grow into membrane ruffles on lamellipodia once associated at the cell surface, monocyte receptors ( uPA-R urokinase plasminogen activator receptor) becomes associated with microfilaments via vinculin. Switching, of the cell phenotype to one that no longer secretes 'dedifferentiation' involves extracellular matrix found in normal cartilage binding interactions with isoforms (syndecan)and tenascin-C¤ and other extracellular matrix proteins. A novel protein termed vinexin as a vinculin-binding protein can enhance actin cytoskeletal organization and cell spreading. The 2 proteins vinculin and metavinculin and synemin a cardiac-specific phenotype sequences exhibit a high level of sequence identity (greater than 95%) the N-terminal core (seven-helical bundle domain (Vh1)) and the C terminus of the molecule outside this different vinculin-derived peptide in the C-terminal half of the molecule is consistent with 2 purified proteins anatomically variable and other markers for embryologic origin close to the inner leaflet of the ventral plasma membrane with 2 proteins arising from a single vinculin gene via alternative splicing at the mRNA level with short vinculin cDNA fragments (glial fibrillary acidic protein) neurofilament, desmin and laminin were not expressed. Vinculin is activated only at sites of cell adhesion when vinculin, a focal adhesion protein that is activated by interacting with each of the three* vinculin-binding sites peptide* from talin binding, the talin-vinculin system contains binding sites (VBS) that can bind three vinculin-binding site individually to the vinculin head (Vh) domain talin.

Hellenistic_Pagan  due to confusion [and (deity-Samyaza) only Mysteries of Mithras http:/alfetn.net/vb3/showthread.php?t=18920&page=5RNA interference in diverse organisms ranging from Arabidopsis like genetic interaction amplitude to human and spermatogonial cell surface markers Thy-1 [thymus cell antigen 1], these cells share elements of common molecular machinery that is focused on the histological distribution of the beta 1-integrins in the human thymus VLA-6 selectively stained a single flattened epithelial cell layer (perilobular epithelial cells) demarcating the peripheral cortex from the surrounding perivascular compartment. Neuron-specific protein gene product 9.5 (PGP9.5 ubiquitin carboxyl-terminal esterase L1 (ubiquitin thiolesterase)) can span nine exons and posesses the same properties in common with (ITGA6); human fetal liver EpCAM +ve cells [tumor-associated calcium signal transducer 1] were positive for CD90 (Thy 1; §§) when hepatic markers were studied, it contains only three introns that do not define protein domains, it contains nine exons and displays 5' features some common to many genes and some common with neurofilament neuron-specific enolase and Thy-1-antigen gene 5' regions.

    Tetrachloro-dibenzo-p-dioxin (TCDD) is an ubiquitously distributed xenobiotic, mediated by modulation of the thymic microenvironment. Dose-dependent increases were observed in integrin chain and TGF-beta(1) contents. The sorted cells were contained in the CD49f+[integrin 6, DFKZp7; §§]/Thy-1+ fraction. The thymic microenvironment consists of a network (through the lamina lucida of the digestive basement membrane) of interrelated cells. Because interepithelial, epithelial-macrophage, and lymphocyte-epithelial cell interactions are important for thymocyte differentiation. This phenotypic profile generally corresponds to the (extended Bedouin family) distribution of integrin and other receptor molecules (of the triple syndrome OMIM 226730; CD49f) on thymic epithelial cells in tissue sections.

    Laminin and type IV collagen, are not restrictedly located at typical basement membrane sites, also forming a thick network in the medullary region of the thymic lobules, most of them belong to the integrin type in the thymus understands [traffic, differentiation, death and survival], not only in normal, but also in pathological conditions.

    Too Little Nursing Too Late downstream of ITBG4 another Basement Membrane Zone Hitchiked Exon 7 Zone Artresia.

    ITGB4(concept of the philosopher-king as being rule by schoolmasters) All Hail Gaius Caesar Caligula Scum of the Earth http:/flickr.com/photos/8860599@N08/2804652151; Recently in the corresponding genes, beta4 integrin (ITGB4; §§) is altered at the dermal-epidermal basement-membrane zone; showed cross-talk (ITGA6 and ITGB4) have been disclosed in a limited number of patients at the dermal-epidermal basement-membrane zone. recently, VLA-6 was identified primarily in the basement membrane of vessels. The moAb for VLA-6 stained the basement membrane of the bronchial epithelium, putative pathogenic mutations, however direct nucleotide sequencing, did not reveal sequence variants in ITGA6 §§, were identified in both ITGB4 allels; found in T cells infiltrating the basement membrane zone.

    (ITGB4; 147557) or the integrin-alpha-6 gene (ITGA6; 147556) 17q11-qter, 2q31.1, pyloric atresia is a primary manifestation rather than a scarring process secondary to JEB , excluding the Herlitz form of JEB the GB3 monoclonal antibody which reacts to laminin-5 subunits, of the triple syndrome epidermolysis bullosa/pyloric atresia/aplasia cutis congenita (EB-PA-ACC); premature termination codons in both alleles being characteristic of lethal variants. Affected ITGB4 individuals were members of the extended [OMIM 226730] Bedouin family from consanguineous Bedouin parents. The sequence of events appeared to be initiated by the separation of the epidermis or the intestinal mucosal layer. Demonstrate for the ITGB4 mutations in nonlethal phenotype of epidermolysis bullosa with congenital pyloric atresia. The ITGB4 mutation reports to help define genotype--phenotype correlation in this rare genodermatosis and altered basement membrane zone atresia.

    Beta4 integrin, is an integral component of hemidesmosomes. Putative pathogenic mutations, however, were identified in both ITGB4 alleles a 1-bp maternal deletion, 3434delT, and an 8-bp paternal deletion, 4050de18 heterozygote for the beta4 missense mutation (L156P) and a nonsense mutation (R554X) in the extracellular domain of the beta4 integrin subunits at the cutaneous basement membrane zone of an autosomal recessive blistering disorder included another homozygous 2-bp deletions, it contributes to the stable association of epidermis with the underlying basement membrane. Because beta 4 integrin is expressed not only in the skin but also in the epithelial lining of the stomach. These results contribute to further the accumulation of exon-mutation data of the 7-11 genotype/phenotype correlation in PA-JEB, exon 7 is not present in the liver. And no other exogenous exons could be fused to detected and nearly arrhythmic RNAi promoters fused to 2 DNA variant exon 7 and a ins/del in intron 8 of CREB (downstream) cycle hitchiked as adenovirus as compared with adenocarcinoma is suggested in exon 11, exon 7 is all that differentiates two genes and the phenotype effects is heterozygosity for ITGB4 missense and nonsense mutations is followed by the heteroduplex formation, creation of such elements is [context dependent] comprising all three subtypes when compared with high mortality ECM-ITGB6 references can be implicated in induction of apoptosis (including NK natural killer cells) of the specific microcompartment, in which the metabolisim of the potentially toxic (ethanol-regulated genes) by products takes place, but are modulated here in such a way that suggests induction of resistance against apoptosis.

    CD19 B4 Surface Antigens Dark Basement Idiotypic Molecular Mimicry

    The Idiocracy talks about German New MedicineAcute myeloid leukemia (AML) with t(8;21)(q22;q22) frequently express the B-cell antigen CD19: [§§] catalytic and translocation domains of diphtheria toxin (DT(390)) fused to two repeating sFv subunits recognizing CD19. The amino acid sequence showed no significant homology with other known proteins, but the putative extracellular region contained 2 Ig-like domains, indicating that CD19 is a new member of the Ig superfamily. BsAb were directed against immunoglobulin-idiotype (Id), major histocompatibility refers to MHC class II or CD19 as indicated by MK-167 or Ki67 immunostaining.

    An idiotype is a shared characteristic between a group of immunoglobulin or T cell receptor (TCR) molecules based upon the antigen binding specificity. The term idiotype is sometimes used to describe the collection of multiple idiotopes repertoire of (CD19 (high)) survival molecules and (CD95 (low/-), Bcl-2(+)), and overall antigen binding capacity, possessed by an antibody. The morphological findings were uniform: STS 25 cells express the idiotypic (Id+) immunoglobulin (Ig) specific for the HLA class I and II that do not secrete phages. They were positive for CD19 and HLA-DR class II. No age-related differences in the parameters evaluated were detected between elderly group and controls. Therefore, these data suggest that the altered expression of Pax-5, but not E2A or Id, is responsible for the loss of CD19 expression in human myeloma cells, although the underlying mechanism of the altered Pax-5 gene expression remains to be clarified. This model was subsequently used to evaluate monoclonal antibodies (MoAb) B43 reactivity with anti-human CD19 MoAb, BCL-1 cells efficacy of B43 MoAb conjugated to the plant hemitoxin pokeweed antiviral protein (PAP).
