disease:Defects in ABCC2 are the cause of Dubin-Johnson syndrome (DJS) [MIM:237500]. DJS is an autosomal recessive disorder characterized by conjugated hyperbilirubinemia, an increase in the urinary excretion of coproporphyrin isomer I, deposition of melanin-like pigment in hepatocytes, and prolonged retention of sulfobromophthalein, but otherwise normal liver function.,function:Mediates hepatobiliary excretion of numerous organic anions. May function as a cellular cisplatin transporter.,similarity:Belongs to the ABC transporter family. Conjugate transporter (TC 3.A.1.208) subfamily.,similarity:Contains 2 ABC transmembrane type-1 domains.,similarity:Contains 2 ABC transporter domains.,tissue specificity:Found on the apical membrane of polarized cells in liver, kidney and intestine. The highest expression is found in liver.,
Apical cell membrane ; Multi-pass membrane protein .
Expressed by polarized cells in liver, kidney and intestine. The highest expression is found in liver.
