| Application: | Activin A human has been used as a constituent of modified barth′s saline used in in vitro induction of pronephros. It has also been used as a constituent of Roswell Park memorial institute (RPMI) media to induce pancreatic differentiation of multipotent dermal fibroblasts in vitro. |
| Biochem/physiol Actions: | Activins play a vital role in the regulation of hormonogenesis, cellular homeostasis and differentiation programs. Elevated expression of activin A and B leads to the loss of muscle mass. Both activin A and B have a potential to act as a serum markers of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). |
| General description: | Activin A gene with two exons is mapped to human chromosome 2q35. Activin A also known as inhibin α-subunit belongs to the TGF-β (transforming growth factor-β) superfamily of proteins and its expression is exclusive to gonads, placenta and adrenal cortex. |
