UniProtKB - A2RTF1 (CTSRB_MOUSE)
Protein
Cation channel sperm-associated protein subunit beta
Gene
Catsperb
Organism
Mus musculus (Mouse)
Status
Functioni
Probably 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.1 Publication
Miscellaneous
CatSperb is absent in sperm from mice lacking CatSper1, suggesting that stable expression of CatSperb protein requires CatSper1.1 Publication

Expressioni
Tissue specificityi
Testis-specific. Specifically present in the principal piece of sperm tail (at protein level). Specifically expressed in the seminiferous tubules but not in the interstitial cells. Within the tubules, it is expressed in spermatocytes and spermatids, but not in spermatogonia.1 Publication
