FLRG (follistatin-related gene; 3)

Follistatin/Osteonectin-like EGF domain, the FSTL3 gene chromosome 19p13: [§§; †, ␠]. FLRG (follistatin-related gene; 3) found to be stored in secretory granules of the cells, encodes contains 2 cysteine-rich secretory proteins functioning as a secreted glycoprotein once bound to 2 potential N-glycosylation sites an exon/intron domain structure both the activin domain its propeptide (WFIKKN2) of the C terminus and FSTL3 inhibited BMP2, it is related to the class 1-1 complex free inhibitor follistatin modules functioning as a 27 kD secreted glycoprotein involved in the TGFbeta-inducible expression of the FLRG gene, or by transfection with Smad protein effects on hematopoiesis during erythropoiesis, promoting the primary mechanism of action to bioneutralizeº activin for both follistatin (FS) and FS-like 3 (FSTL-3) modulation of activin (ActRIIs),  myostatin, and other TGF beta superfamily signaling and uniquely with phosphatidylinositol 3-kinase a hypothetical complex activity in pseudogeneº secretory function composed of a protein family of extracellular matrix-associated glycoproteins functioning as a secreted glycoprotein.
