GnRH-1 neuronal activity is independent of HCN channels but is sensitive to PKA-dependent phosphorylation.
Pulsatile release of gonadotropin-releasing hormone-1 (GnRH-1) stimulates the anterior pituitary and induces secretion of gonadotropin hormones. GnRH-1 release is modulated by many neurotransmitters that act via G protein-coupled membrane receptors. cAMP is ...
