Activin A Protein, Human (Biotinylated, HEK293, Avi)
Based on 1 publication(s) in Google Scholar
The INHBA protein plays a key role in regulating pituitary function by regulating follicle-stimulating hormone secretion together with activin. Its broad effects span a variety of physiological processes, including hormone secretion, germ cell development, erythrocyte differentiation, insulin secretion, nerve cell survival, embryonic development, and bone growth, depending on unique subunit composition. Activin A Protein, Human (Biotinylated, HEK293, Avi) is the recombinant human-derived Activin A protein, expressed by HEK293, with C-Avi labeled tag.

Background
INHBA protein assumes a pivotal role in the intricate regulation of pituitary gland function, contributing to the opposing dynamics of inhibiting and activating follitropin secretion alongside activins. The expansive influence of inhibins and activins, with INHBA as a central player, spans a spectrum of physiological processes, including hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development, and bone growth, contingent upon their unique subunit compositions. Notably, inhibins, such as Inhibin A and Inhibin B, emerge as counterparts opposing the functions of activins. Structurally, INHBA exists in a dimeric form, intricately linked by one or more disulfide bonds, representing a homodimer of beta-A subunits. The diversity of activins, encompassing Activin A, Activin B, and Activin AB, further emphasizes their specific subunit compositions, influencing interactions with regulatory proteins like FST and FSTL3. This intricate interplay underscores INHBA's central role in orchestrating a finely tuned regulatory network governing diverse physiological functions.
