These junctions are comprised of sets of continuous networking strands in the outwardly facing cytoplasmic leaflet, with complementary grooves in the inwardly facing extracytoplasmic leaflet. The protein encoded by this gene, a member of the claudin family, is an integral membrane protein and a component of tight junction strands. It is found primarily in the kidneys, specifically in the thick ascending limb of Henle, where it acts as either an intercellular pore or ion concentration sensor to regulate the paracellular resorption of magnesium ions. Defects in this gene are a cause of primary hypomagnesemia, which is characterized by massive renal magnesium wasting with hypomagnesemia and hypercalciuria, resulting in nephrocalcinosis and renal failure. This gene and the CLDN1 gene are clustered on chromosome 3q28. [provided by RefSeq, Jun 2010]. * **UniProt Summary**: 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. |PMP22 Claudin| |magnesium ion transmembrane transporter activity| |magnesium ion transmembrane transport| |magnesium ion transport| |calcium-independent cell-cell adhesion via plasma membrane cell-adhesion molecules| |excretion| |bicellular tight junction| |structural molecule activity| |cell-cell adhesion via plasma-membrane adhesion molecules| |divalent metal ion transport| |divalent inorganic cation transport| |cell-cell adhesion| |cellular metal ion homeostasis| |inorganic cation transmembrane transport| |cation transmembrane transport| |metal ion homeostasis| |cellular cation homeostasis| |metal ion transport| |cellular ion homeostasis| |inorganic ion transmembrane transport| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |ion homeostasis| |cation transport| |cellular homeostasis| |cell adhesion| |biological adhesion| |ion transmembrane transport| |identical protein binding| |chemical homeostasis| |transmembrane transport| |ion transport| |homeostatic process| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp275|Citral 75μM R06 exp275]]|1.75| No correlation found to any other genes in chemogenomics.
