Cation channel sperm-associated protein subunit zeta

Gene

CATSPERZ

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Auxiliary component of the CatSper complex, a complex involved in sperm cell hyperactivation. Sperm cell hyperactivation is needed for sperm motility which is essential late in the preparation of sperm for fertilization. Required for a distribution of the CatSper complex in linear quadrilateral nanodomains along the flagellum, maximizing fertilization inside the mammalian female reproductive tract.By similarity

Caution

A report observed N-glycosylation at Asn-58 (PubMed:19139490). However, as the protein is not predicted to localize in an extracellular compartment of the cell, additional evidences are required to confirm this result.1 Publication
