CatSper3 (CatSper channel 3) is a member of the CatSper (cation channel of sperm) family of ion channels, which are important for male fertility. These channels are primarily expressed in sperm cells and are crucial for processes such as sperm motility and the ability of sperm to navigate toward the egg during fertilization. CatSper channels are calcium-permeable ion channels that help regulate intracellular calcium levels in sperm.
