CC Name=C2;
CC IsoId=P13808-5; Sequence=VSP_000459, VSP_000461;
CC -!- TISSUE SPECIFICITY: Isoform a is widely expressed at similar levels in
CC all tissues examined. Isoforms B1 and B2 are predominantly expressed in
CC stomach although they are also detected at lower levels in other
CC tissues. Isoform C1 is stomach-specific. Isoform C2 is expressed at
CC slightly higher levels in lung and stomach than in other tissues.
CC {ECO:0000269|PubMed:11006093}.
CC -!- SIMILARITY: Belongs to the anion exchanger (TC 2.A.31) family.
CC {ECO:0000305}.
