The FSH beta protein, in conjunction with the alpha chain CGA, forms follitropin, also known as follicle-stimulating hormone (FSH). This hormone is crucial for follicle development and spermatogenesis within reproductive organs. It binds to FSHR, a G protein-coupled receptor on target cells, initiating downstream signaling pathways. The intricate assembly of FSH beta within the hormone heterodimer underscores its essential contribution to reproductive processes and hormonal signaling cascades.
