CC   -!- FUNCTION: Plays a major role in tight junction-specific obliteration of
CC       the intercellular space, through calcium-independent cell-adhesion
CC       activity. Involved in paracellular magnesium reabsorption. Required for
CC       a selective paracellular conductance. May form, alone or in partnership
CC       with other constituents, an intercellular pore permitting paracellular
CC       passage of magnesium and calcium ions down their electrochemical
CC       gradients. Alternatively, it could be a sensor of magnesium
CC       concentration that could alter paracellular permeability mediated by
CC       other factors (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell junction, tight junction. Cell membrane;
CC       Multi-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the claudin family. {ECO:0000305}.
