Protein Structure
UniProt Annotation
Function Voltage-gated calcium channel that plays a central role in sperm cell hyperactivation. Controls calcium entry to mediate the hyperactivated motility, a step needed for sperm motility which is essential late in the preparation of sperm for fertilization. Activated by intracellular alkalinization. Contrary to the human ortholog, not activated by progesterone. {ECO:0000269PubMed:17227845, ECO:0000269PubMed:17344468}.
Subcellular Localization Cell projection, cilium, flagellum membrane {ECO:0000269PubMed:16107607, ECO:0000269PubMed:17227845}; Multi- pass membrane protein {ECO:0000269PubMed:16107607, ECO:0000269PubMed:17227845}. Note=Specifically located in the principal piece of sperm tail.
