General description

Gonadotropin-releasing hormone I (also known as GnRH, GnRH-I, Gonadoliberin-1, Gonadoliberin I, LHRH, LH-RH I, Luteinizing hormone-releasing hormone I) is encoded by the Gnrh1 (also known as Gnrh, Lhrh1, Lnrh) gene (Gene ID 14714) in murine species. GnRH/LHRH is initially produced as a 90-amino acid progonadoliberin-1 precursor protein (UniProt P13562), removal of the signal peptide (a.a. 1-21) yields progonadoliberin-1 (a.a. 22-90), which is further processed by a proteolytic cleavage to release the GnRH/LHRH decapeptide (a.a. 22-31) and the 56-a.a. prolactin release-inhibiting factor 1 (a.a. 35-90). The LHRH decapeptide functions as the primary endocrine link between the brain and the reproductive system. It plays a primary neuroendocrine role in orchestrating the developmental processes associated with sexual development in immature mammals and also in maintaining normal reproductive function in adults. LHRH-producing neurons are located mainly in the lateral anterior hypothalamus, septum, and medial preoptic area, from where they extend axons towards the median eminence and relese the hormone into the hypothalamo-hypophyseal portal blood vessels in an episodic or pulsatile manner.

Specificity

Clone HU11B reacts with C-terminally blocked GnRH-I/LHRH (LHRH-NH2), but not LHRH with a free C-terminal end (LHRH-COOH). Clone HU11B exhibits reduced affinity toward N-terminally truncated LHRH-NH2 and failed to recognize pro-LHRH, Atrial Naturetic Factor/ANF, Growth hormone-releasing hormone/GHRH, Oxytocin, Somatostatin, Thyrotropin-releasing hormone/TRH, and Vasoactive intestinal peptide/VIP (Urbanski, H.F., et al. (1991). Biol. Reprod. 44(4):681-686).
