Recombinant Human GDF-8 Protein

Description
Growth and Differentiation Factors (GDF) are members of the BMP family of TGF-beta superfamily. This group of proteins is characterized by a polybasic proteolytic processing site that is cleaved to produce a mature protein containing seven conserved cysteine residues. The members of this family are regulators of cell growth and differentiation in both embryonic and adult tissues. Studies in rodents suggest that this protein is involved in the establishment of left-right asymmetry in early embryogenesis and in neural development in later embryogenesis.
GDF-8, also known as Myostatin, is a myokine, a protein that is produced and released by myocytes that act on the autocrine functions of muscle cells to inhibit muscle cell growth and differentiation. In humans, it is encoded by the MSTN gene. Myostatin is a secreted growth differentiation factor that is a part of the TGF beta protein group.
