Tissue SpecificityIsoform 1 is expressed in the jejunum, ileum, cecum and ascending colon intestine. Isoform 2 is xpressed in the gallbladder, duodenum, jejunum, ileum, cecum, ascending, transverse and descending colon, sigmoid colon and rectum. Isoform 2 is expressed in colorectal adenocarcinomas and their adjacent normal mucosa (at protein level). {ECO:0000269|PubMed:17909007, ECO:0000269|PubMed:7588781, ECO:0000269|PubMed:7619861}.
