TissueNA
Tissue SpecificityDetected in several tissues with higher expression in placenta, kidney and peripheral blood leukocytes (PubMed:15659399). In the kidney, is detected in epithelial cells of the distal tubule and collecting duct (PubMed:15659399). In the intestine, is expressed mainly in crypt cells of the intestinal microvilli and epithelial cells in the base of the villus (PubMed:15659399). {ECO:0000269|PubMed:15659399}.
