Identification
HMDB Protein ID CDBP02855
Secondary Accession Numbers Not Available
Name Cation channel sperm-associated protein 4
Description Not Available
Synonyms
  1. CatSper4
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
