Tissue SpecificityExpressed predominantly in the intestinal epithelium. Expressed in luminal cells of colonic mucosa. Also expressed in the Merkel cells of keratinized oral mucosa;
specifically at the tips of some rete ridges of the gingival mucosa, in the basal layer of the palatal mucosa and in the taste buds of lingual mucosa. {ECO:0000269|PubMed:10973561, ECO:0000269|PubMed:1696264}.
