Protein
Calcium-transporting ATPase 1, endoplasmic reticulum-type
Organism
Arabidopsis thaliana
Function
This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the endoplasmic reticulum lumen. Also regulate manganese ion homeostasis by pumping it into endomembrane compartments. Can also transport zinc.
Similarity
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIA subfamily.
