The protein shows tissue specific expression, shown on a blot included in Wu et al. (2000). Lowest amounts of ECA1 are found in siliques.
Calcium-transporting ATPase 1, ER type, is a magnesia-dependent enzyme that catalyzes the hydrolysis of ATP while transporting calcium from the cytosol to the endoplasmic tube. The balance of manganese ions is also regulated by pumping into the membrane cavity. This enzyme can also transport zinc. Aliases :ACA3, Arabidopsis er CA2+ -ATPase 1,ATECA1, ECA1, er CA2+ -ATPase 1.
