Myostatin , also known as growth and differentiation factor 8 (GDF8)
a TGF-beta
family member is (an inhibitor of myogenesis) secreted into the plasma expressed in human
skeletal muscle
(expressed in many different muscles
throughout the body) as a 12.5-kD propeptide
and a 26-kD glycoprotein (myostatin-immunoreactive protein) a dimer
(threeexons and two
introns) locus: 2q32.2 [§§; ^] and WFIKKN2 protein (WAP, follistatin/kazal, kunitz, immunoglobulin, and netrin domain (WFIKKN2) containing 2) binds
mature GDF8/myostatin and myostatin propeptide WFIKKN1 the paralogue
(functional overlap) of these proteins. Myostatin

is the biologically active portion of the protein that hSGT
(human small glutamine-rich tetratricopeptide repeat-containing
protein) may play a role in regulation, and complexes with
amyloid-beta like signal sequence. Myostatin circulates as part of a
latent complex containing follistatin-related gene FLRG. Activin type II receptors (ActRIIs) transmit the activin-binding protein (FLRG)

IIB and the myostatin propeptide is known to bind and inhibit
myostatin in vitro.
GLP1 receptor (GLP1R) a seven-transmembrane
family B
G protein-coupled receptor (GPCR) locus : 6p21.2 [§§; ^],
with a N-terminal
extracellular domain is a
potent insulinotropicincretin
hormone important in maintaining bloodglucose
homeostasis, through their receptors, GLP1R and glucose-dependent
insulinotropic polypeptide GIPR. The
glucagon-like peptide-1 (GLP-1) C-terminal
regions bind
to the N terminus (NTD) this region of interaction
is mediated
by the nGLP1R
(receptor variants) released from the gut
as an incretin

inhibitors are structurally related gastrointestinal hormone
secreted from enteroendocrineL
cells into the blood

GLP-1R and the GIP

of these proteins, is neuroprotective.
GLP1 and GLP1R are expressed in the brain and
associated mechanisms
in the central nervous system,
regulation of neuroendocrine
and behavioural responses in certain cells
in the brain. TCF7L2
and GLP1R/GIPR expression effects on beta-cell
function was decreased in human T2DM islets
is a characteristic feature of NIDDM. GLP-1 stimulate secretion of
pituitary hormones. GLP1 is a hormone derived from the preproglucagon
molecule (GCG).
