FAMILY

cation transport ATPase (P-type) (TC 3.A.3) family

DESCRIPTION

Also known as AT2B4_HUMAN, ATP2B4, ATP2B2, MXRA1. Calcium/calmodulin-regulated and magnesium-dependent enzyme that catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell (PubMed:8530416). By regulating sperm cell calcium homeostasis, may play a role in sperm motility (By similarity). Interacts with PDZD11 (PubMed:12763866). Interacts with SLC35G1 and STIM1 (PubMed:22084111). Interacts with calmodulin (PubMed:2963820, PubMed:10493800).
