Gene Name
| CATSPER4 |
Protein Type
| Transporter |
Biological Properties |
General Function
| Involved in ion channel activity |
Specific 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 |
