Protein: Calcium-transporting ATPase 3, endoplasmic reticulum-type (AtECA3) (EC 7.2.2.10) (Q9SY55)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to an endomembrane compartment (Probable). Involved in calcium-enhanced root growth, in tolerance to toxic levels of manganese and in secretory processes. Has a crucial role in manganese nutrition, but is not involved in transporting copper, iron or zinc.
