NCIt definition : Inhibin alpha chain (366 aa, 40 kDa) is encoded by the human INHA gene. This protein
is involved in the negative regulation of the secretion of follitropin by the pituitary
gland.;
NCIt note : The inhibin alpha chain joins either the beta A or beta B subunit to form either Inhibin-A
or Inhibin-B, respectively. Both Inhibin heterodimers inhibit follitropin secretion.;
