Human/Cynomolgus/Mouse/Rat GDF-8 Protein (GDF-HM008) Summary
Product Description |
Recombinant Human/Cynomolgus/Mouse/Rat GDF-8 Protein is expressed from HEK293 without tag.It contains Asp267-Ser375 (Human/Cynomolgus) / Asp268-Ser376 (Mouse/Rat). |
Product Background |
Growth/differentiation factor 8 (GDF8), or myostatin, negatively regulates muscle mass. GDF8 is held in a latent state through interactions with its N-terminal prodomain. GDF8, like numerous TGF-β family members, is a disulfidelinked dimer that is synthesized as a precursor protein which requires cleavage by a furin-like protease to yield an N-terminal prodomain and a C-terminal mature, signaling domain. |
