Gene: SLC4A1 (solute carrier family 4 member 1 (Diego blood group)) Homo sapiens
Symbol: SLC4A1
Name: solute carrier family 4 member 1 (Diego blood group)
Description: Exhibits anion transmembrane transporter activity; ankyrin binding activity; and protein homodimerization activity. Involved in bicarbonate transport. Localizes to the basolateral plasma membrane; cortical cytoskeleton; and integral component of plasma membrane. Implicated in congenital hemolytic anemia; hereditary spherocytosis; hereditary spherocytosis type 4; malaria; and renal tubular acidosis. Biomarker of glucosephosphate dehydrogenase deficiency and hereditary elliptocytosis.
Type: protein-coding
RefSeq Status: REVIEWED
