Protein Structure

UniProt Annotation

Function

May be involved in forming the receptor site for cardiac glycoside binding or may modulate the transport function of the sodium ATPase.

Subcellular Localization

Membrane {ECO:0000305}; Single-pass type III membrane protein {ECO:0000305}.

Disease Associations

Hypomagnesemia 2 (HOMG2) [MIM:154020]: A disorder due to primary renal wasting of magnesium. Plasma levels of other electrolytes are normal. The only abnormality found, in addition to low magnesium levels, is lowered renal excretion of calcium resulting in hypocalciuria. {ECO:0000269PubMed:11062458}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Expressed in the distal convoluted tubule in the kidney. Found on basolateral membranes of nephron epithelial cells.
