TissueNA
Tissue SpecificityWidely expressed, with high levels in heart, skeletal muscle and kidney. Detected at high levels in bronchial brushings and in normal lung (at protein level). In fetal lung tissue, expressed in the developing bronchial lumen lining cells (at protein level). Tends to be down-regulated in lungs affected by inflammatory diseases or neoplasia (at protein level). Expressed in immune cells, including B and T lymphocytes and macrophages. {ECO:0000269|PubMed:11978965, ECO:0000269|PubMed:12073013, ECO:0000269|PubMed:24488492}.
