Anti-Inhibin Beta B (INHbB)

Inhibin, beta B is a protein which in humans is encoded by the INHBB gene.INHBB is a subunit of both activin and inhibin, two closely related glycoproteins with opposing biological effects.Inhibins are heterodimeric glycoproteins composed of an a subunit (INHA) and one of two homologous, but distinct, b subunits (bA or bB, this protein). mRNA for the two subunits has been demonstrated in the testes of adult rats.Inhibin can bind specifically to testicular interstitial cells throughout development and may be an important regulator of Leydig cell testosterone production or interstitial cell function.The inhibin beta B subunit joins the a subunit to form a pituitary FSH secretion inhibitor. Inhibin has been shown to regulate gonadal stromal cell proliferation negatively and to have tumour-suppressor activity.
