产品介绍 background:
CatSpers are ion transport proteins located on the surface of sperm cells in the principal piece of the sperm tail. CatSpers are vital to sperm motility, fertilization and cAMP-mediated calcium influx in sperm. There are four CatSper proteins in mammalian sperm, namely CatSper (or CatSper1), CatSper2, CatSper3 and CatSper4. CatSper proteins are believed to assemble into a heterotetrameric complex, forming an alkalinization-activated Ca2+-selective channel. CatSper∫ is a multipass membrane protein that functions as an auxiliary protein of the CatSper channel. It contains a large extracellular domain and a number of N-glycosylation sites. CatSper∫ specifically interacts with CatSper1 and through this interaction plays an important role in the hyperactivated motility of sperm cells, a process that is required in the preparation of sperm for fertilization.

Function:
RelevanceCATSPERB is a component of a complex composed at least of CATSPER1, CATSPERB, CATSPERG and HSPA1B. CATSPERB contains at least 2 transmembrane domains and 8 N-glycosylation sites. CATSPERB is required for trafficking or formation of a stable channel complex. It is involved in sperm cell hyperactivation via its association with CATSPER1. Sperm cell hyperactivation is needed for sperm motility which is essential late in the preparation of sperm for fertilization. There are 2 isoforms produced by alternative splicing.
