Protein Details: Cation channel sperm-associated auxiliary subunit gamma 2

Protein ID

ICDB_Pro_0103

Protein Name

Cation channel sperm-associated auxiliary subunit gamma 2

Gene Name

Catsperg2; Catsperg

Organism

Mus musculus (Mouse)

Length

1145 amino acids

AlphaFoldDB

AF-C6KI89-F1-model_v4.pdb

Function

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.
