Protein attributes

Sequence length	1220 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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+(Cis) = ADP + phosphate + Ca2+(Trans).
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Isoforms XE and 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) family. Type IIB subfamily.

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)

     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;
