Function Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity. Involved in paracellular magnesium reabsorption. Required for a selective paracellular conductance. May form, alone or in partnership with other constituents, an intercellular pore permitting paracellular passage of magnesium and calcium ions down their electrochemical gradients. Alternatively, it could be a sensor of magnesium concentration that could alter paracellular permeability mediated by other factors.
Subcellular Localization Cell junction, tight junction. Cell membrane; Multi-pass membrane protein.
Disease Associations Hypomagnesemia 3 (HOMG3) [MIM:248250]: A progressive renal disease characterized by primary renal magnesium wasting with hypomagnesemia, hypercalciuria and nephrocalcinosis. Recurrent urinary tract infections and kidney stones are often observed. In spite of hypercalciuria, patients do not show hypocalcemia. {ECO:0000269PubMed:10390358, ECO:0000269PubMed:10878661, ECO:0000269PubMed:11518780}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Kidney-specific, including the thick ascending limb of Henle (TAL).
