Chloride/bicarbonate exchanger. Mediates the efficient absorbtion of chloride ions in the colon, participating in fluid homeostasis. Defects in SLC26A3 are the cause of diarrhea type 1 (DIAR1); also known as congenital chloride diarrhea (CLD). DIAR1 is a disease characterized by voluminous watery stools containing an excess of chloride. The children with this disease are often premature. Belongs to the SLC26A/SulP transporter (TC 2.A.53) family. Note: This description may include information from UniProtKB.
