Theses and Dissertations
Two biologically active peptides, gonadotropin releasing hormone (GnRH) and GnRH associated peptide (GAP) are both derived from a common prohormone precursor protein, pro-GnRH/GAP. Both peptides are cosecreted from hypothalamic neurosecretory granules and are involved in the regulation of mammalian reproduction. A calcium dependent, neutral pH serine protease discovered in this laboratory, GAP-releasing enzyme, is the most likely processing enzyme of pro-GnRH/GAP. GAP-releasing enzyme is immunologically related to PC1/3, a member of the prohormone convertase (PC) class of processing endoproteinases.
GAP-releasing enzyme recognizes the eight residue processing site within pro-GnRH/GAP, G6LRPGGKR13, and correctly cleaves the R13 …
