Inhibin secretion is diminished by GnRH, and enhanced by insulin-like growth factor-1 (IGF-1). In males. It is secreted from the Sertoli cells, located in the seminiferous tubules inside the testes. Androgens stimulate inhibin production; this protein may also help to locally regulate spermatogenesis. Mechanism of … Visa mer Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Identified in 1986, activin enhances FSH biosynthesis and secretion, and participates in the regulation of the Visa mer The activin and inhibin protein complexes are both dimeric in structure, and, in each complex, the two monomers are linked to one another by a single disulfide bond. In addition, both … Visa mer Activin 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: Visa mer Activin Activin is produced in the gonads, pituitary gland, placenta, and other organs: • In the ovarian follicle, activin increases FSH binding and … Visa mer Activin Activin A is more plentiful in the adipose tissue of obese, compared to lean persons.
