Accession ID	Name	Pfam Type
PF21548	CATSPER subunit beta protein 2nd domain	domain

This entry represents the beta-propeller domain from the Cation channel sperm-associated protein subunit beta protein. The cation channel of sperm (CatSper) is essential for sperm motility and fertility. The auxiliary subunit beta contains a single transmembrane segment and a large extracellular region.
