  Definition"A protein that is a translation product of the human CATSPERB gene or a 1:1 ortholog thereof. Members of this class are auxiliary proteins to the CatSper channel. They have four putative transmembrane-spanning domains. In mammals, four CatSper ion channel subunit genes (CatSpers 1-4) are required for sperm cell hyperactivation and male fertility. The four proteins assemble (presumably as a tetramer) to form a sperm-specific, alkalinization-activated Ca(2+)-selective channel." [PMID:17478420, PRO:CNA]
