TissueNA
Tissue SpecificityExpressed 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. {ECO:0000269|PubMed:10362588, ECO:0000269|PubMed:10437792, ECO:0000269|PubMed:10554024, ECO:0000269|PubMed:11262615, ECO:0000269|PubMed:11320086, ECO:0000269|PubMed:14966209, ECO:0000269|PubMed:15707651, ECO:0000269|PubMed:16158324}.
