It does the opposite as inhibin. Many other functions have been found to be exerted by activin, including their roles in cell proliferation, differentiation, apoptosis[1], metabolism, homeostasis, immune response, wound repair[2], and endocrine function Image File history File links No higher resolution available. ...

Structure
Activin contains two beta subunit that are identical to the two beta subunits (A or B) of inhibin, allowing for the formation of three forms of activin: A, AB, and B. They are linked by a single covalent disulfide bond.
Function Activin is produced in the gonads, pituitary gland, placenta and other organs: A sex organ, or primary sexual characteristic, narrowly defined, is any of those parts of the body (which are not always bodily organs according to the strict definition) which are involved in sexual reproduction and constitute the reproductive system in an complex organism; namely: Male: penis (notably the glans penis...

Mechanism As with other members of the superfamily, activins interact with two types of cell surface transmembrane receptors (Types I and II) which have intrinsic serine/threonine kinase activities in their cytoplasmic domains. Transmembrane receptors are integral membrane proteins, which reside and operate typically within a cells plasma membrane, but also in the membranes of some subcellular compartments and organelles. ...

Activin binds to the Type II receptor and initiates a cascade reaction that leads to the recruitment, phosphorylation, and activation of Type I activin receptor. This then interacts with and then phosphorylates Smad2 and Smad3, two of the cytoplasmic Smad proteins.
