ProSpec-Activin A Human/CYT-569

Activin Beta-A chain, Erythroid differentiation protein, EDF, FRP, Activin-A, Inhibin-B, Inihibin-Beta A chain.

Inhibins are dimeric peptide hormones produced by female ovarian granulose cells and male Sertoli cells as well as a variety of other tissues. Inhibins have two isoforms, A and B, with the same alpha subunit but different beta subunits. Inhibin A is a dimer of alpha and beta A subunits, inhibin B is a dimer of alpha and beta B subunits.
Inhibins are thought to inhibit the production of follicle-stimulating hormone by the pituitary gland. In addition, Inhibins are also thought to play a role in the control of gametogenesis, and embryonic and fetal development.

抑制素是由雌性卵巢颗粒细胞和雄性支持细胞以及多种其他组织产生的二聚肽激素。 抑制素有两种同工型，A 和 B，具有相同的 α 亚基但不同的 β 亚基。 抑制素A是α和βA亚基的二聚体，抑制素B是α和βB亚基的二聚体。
抑制素被认为可以抑制垂体产生促卵泡激素。 此外，抑制素还被认为在控制配子发生、胚胎和胎儿发育中发挥作用。
