Recombinant Human/Mouse/Rat MSTN Protein (Asp268-Ser376), GMP-Grade
Product Description
Cat
IMP-9900
Official Symbol
MSLN
Product Overview
Recombinant Human/Mouse/Rat GDF-8/Myostatin protein (Asp268-Ser376) without tag was expressed in Mouse myeloma cell line and
manufactured and tested under current Good Manufacturing Practice (GMP) guidelines.
Description
This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein negatively regulates skeletal muscle cell proliferation and differentiation. Mutations in this gene are associated with increased skeletal muscle mass in humans and other mammals.
