Tissue SpecificityExpressed at highest levels in testis and at lower levels in adrenal gland, bone marrow, brain, colon, heart, kidney, liver, muscle, ovary, pancreas, placenta, prostate, skeletal muscle, skin, small intestine, spleen, stomach, testis, thymus, thyroid and uterus. Expressed in the alveolar epithelium of the lung. Expression is commonly decreased in colon adenocarcinomas and lung cancers. {ECO:0000269|PubMed:10415337, ECO:0000269|PubMed:11278651, ECO:0000269|PubMed:15107820}.
