WebbTwo molecular forms inhibin A and inhibin B is found and have two subunits α and β joined together by a disulfide bond. Inhibin also inhibits the action of the activin by replacing the activin from the activin receptor site. However, the activity of the inhibin is aided by beta glycan that acts as a coreceptor in the complex. WebbInhibins are dimeric glycoproteins composed of an α-subunit and either a βA (inhibin A) or a β B -subunit (inhibin B). The inhibin α-subunit has N -linked glycosylation sites and the glycosylation is essential for inhibin bioactivity (FSH suppressing activity).
WebbInhibin B is a peptide hormone that is produced primarily by growing antral follicles that are responsive to FSH. As the follicle continues to grow and become dominant, inhibin B secretion declines. As the growing pool of antral follicles decreases during aging, levels of inhibin B are diminished. WebbWhereas inhibin (primarily inhibin B) production typically ends following the LH surge in many species, the primate corpus luteum synthesizes and secretes significant amounts of inhibin A. Investigators report immunostaining for inhibin subunits primarily in granulosa luteal but not paraluteal cells; these cells likely produce other members of the inhibin …
