CATSPERE

Gene

Catspere

Protein

Cation channel sperm-associated protein subunit epsilon

Organism

Mus musculus

Length

985 amino acids

Function

Auxiliary component of the CatSper complex, a complex involved in sperm cell hyperactivation (PubMed:28226241). Sperm cell hyperactivation is needed for sperm motility which is essential late in the preparation of sperm for fertilization (PubMed:28226241).

Similarity

Belongs to the CATSPERD family.
