Protein attributes

Sequence length	1020 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol out of the cell or into organelles.
Catalytic activity	ATP + H₂O + Ca²⁺[side 1] = ADP + phosphate + Ca²⁺[side 2].
Enzyme regulation	Activated by calmodulin By similarity.
Subcellular location	Plastid › chloroplast inner membrane; Multi-pass membrane protein Probable.
Tissue specificity	Expressed at higher levels in roots than in leaves.
Domain	The N-terminus contains an autoinhibitory calmodulin-binding domain, which binds calmodulin in a calcium-dependent fashion By similarity.
Sequence similarities	Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily. [View classification]
Sequence caution	The sequence AAF24958.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAA49558.1 differs from that shown. Reason: Erroneous gene model prediction.
