WebAbout Activin: Activin is a protein complex, a gene within the chromosomes 2, 7, and 12 and part of the female endocrine system in humans, though it exists in both sexes. It shares a very close relationship with inhibin, in that they seem to have the completely inverse function though similar mechanisms, structures, and interactions. WebActivin exerts positive effects on FSH by stimulating transcription, biosynthesis, and ultimately secretion as well as stimulating GnRH receptor gene expression. In rodents, after activin binds to gonadotrope …
