Membrane; Multi-pass membrane protein.

Tissue specificity

Ubiquitously expressed at moderate levels.

Sequence similarities

Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IV subfamily. [View classification]

Sequence caution

The sequence BAB15072.1 differs from that shown. Reason: Frameshift at position 997.

The sequence BAB85525.1 differs from that shown. Reason: Contaminating sequence. Sequence of unknown origin inserted in the coding sequence.
