PKDREJ Products

PKDREJ encodes a member of the polycystin protein family. The encoded protein contains 11 transmembrane domains, a receptor for egg jelly (REJ) domain, a G-protein-coupled receptor proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. This protein may play a role in human reproduction. Alternative splice variants have been described but their biological natures have not been determined.; FUNCTION: May have a central role in fertilization. May generate a Ca(2+) transporting channel directly involved in initiating the acrosome reaction of the sperm. SUBUNIT: May form homomultimers or heteromultimers in combination with an as yet unidentified subunits. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.; TISSUE SPECIFICITY: Exclusively expressed in testis.
