Annotation score:3 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

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 evidence is required to confirm this result.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
