Protein attributes
| Sequence length | 1220 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell. |
| Catalytic activity | ATP + H2O + Ca2+[side 1] = ADP + phosphate + Ca2+[side 2]. |
| Subcellular location | |
| Tissue specificity | Isoform XE and isoform XB are the most abundant isoforms and are detected at low levels in brain and fetal skeletal muscle. The other isoforms are only found at lower levels and not in fetal tissues. |
| Sequence similarities | Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily. [View classification] |
Ontologies
Alternative products
| This entry describes 8 isoforms produced by alternative splicing. [Align] [Select] Note: There is a combination of two alternatively spliced domains at N-terminal site A (X and Z) and at C-terminal site C (A, B, E and G). The splice sites have mostly been studied independently. Full isoforms so far detected are isoform XA and isoform XB. Experimental confirmation may be lacking for some isoforms. | ||||||
| Isoform XB (identifier: Q16720-1) Also known as: AIICI; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform XA (identifier: Q16720-2) Also known as: AIICII; The sequence of this isoform differs from the canonical sequence as follows: 1115-1220: IRVVKAFRSS...SPLHSVETSL → MEVVSTFKRS...AGNPGGESVP | ||||||
| Isoform ZA (identifier: Q16720-3) Also known as: AICII; The sequence of this isoform differs from the canonical sequence as follows: 306-319: Missing. 1115-1220: IRVVKAFRSS...SPLHSVETSL → MEVVSTFKRS...AGNPGGESVP | ||||||
| Isoform ZB (identifier: Q16720-4) Also known as: AICI; The sequence of this isoform differs from the canonical sequence as follows: 306-319: Missing. | ||||||
| Isoform XE (identifier: Q16720-5) Also known as: AIICV; The sequence of this isoform differs from the canonical sequence as follows: 1115-1220: IRVVKAFRSS...SPLHSVETSL → MEVVSTFKRS...NPTSAAGSES | ||||||
| Isoform ZE (identifier: Q16720-6) Also known as: AICV; The sequence of this isoform differs from the canonical sequence as follows: 306-319: Missing. 1115-1220: IRVVKAFRSS...SPLHSVETSL → MEVVSTFKRS...NPTSAAGSES | ||||||
| Isoform XG (identifier: Q16720-7) Also known as: AIICVII; The sequence of this isoform differs from the canonical sequence as follows: 1115-1220: IRVVKAFRSS...SPLHSVETSL → VCWDGKKMLRTTEVG | ||||||
| Isoform ZG (identifier: Q16720-8) Also known as: AICVII; The sequence of this isoform differs from the canonical sequence as follows: 306-319: Missing. 1115-1220: IRVVKAFRSS...SPLHSVETSL → VCWDGKKMLRTTEVG |
