Protein attributes
| Sequence length | 1033 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript 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, into the endoplasmic reticulum, or into organelles By similarity. |
| Catalytic activity | ATP + H2O + Ca2+(Side 1) = ADP + phosphate + Ca2+(Side 2). |
| Enzyme regulation | Activated by calmodulin. |
| Subcellular location | Membrane; Multi-pass membrane protein By similarity. |
| Domain | The N-terminus contains an autoinhibitory calmodulin-binding domain, which binds calmodulin in a calcium-dependent fashion. |
| Sequence similarities | Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily. [View classification] |
