Expressed in cornea, skin, vagina, esophagus, and larynx (at protein level). Expressed in trachea and mammary gland. Weakly expressed in testis and kidney. Highly expressed in corneal epithelium, colon and trachea. Moderately expressed in brain, urogenital organs, bladder, uterus and prostate. Highly expressed in tissues containing stratified epithelium including cornea, esophagus, larynx, skin and vagina than those tissues which contain only epithelial monolayers. Expressed in normal breast epithelium but not in breast cancer. Highly expressed during epithelial stratification. Expressed in endothelial cells of lung. Expressed selectively in endothelia of small pulmonary arteries, arterioles, and subpleural and interlobular venules.
Cell membrane; Single-pass type I membrane protein. Basal cell membrane; Single-pass type I membrane protein. Cell junction.; [Calcium-activated chloride channel regulator 2, 109 kDa form]: Secreted. Remains associated to the 35 kDa form until an unidentified event triggers the release.
