Activin-A is a TGF-beta family member that exhibits a wide range of biological activities including regulation of cellular proliferation and differentiation, and promotion of neuronal survival. The biological activities of Activin-A can be neutralized by inhibins and by the diffusible TGF-beta antagonist, Follistatin. Human Activin-A is a 26 kDa disulfide-linked homodimer of two beta A chains, each containing 116 amino acid residues. Elevated levels of Activin-A in human colorectal tumors and in post-menopausal woman have been implicated in colorectal and breast cancers, respectively.
