Tissuebone.marrow, kidney, oviduct, small.intestine, whole.blood
Tissue SpecificityWidely expressed. Highly expressed in whole blood, bone marrow, trachea and fetal liver. Weakly expressed in kidney, skeletal muscle, prostate, lung, pancreas, placenta, heart, uterus, spleen and spinal cord. Highly expressed in intestinal cell types affected by Crohn disease, including epithelial cells. Expressed in CD68 macrophage and CD43 T-cells but not in CD20 B-cells. Predominantly expressed in CD14 cells in peripheral blood mononuclear cells. {ECO:0000269|PubMed:14608356, ECO:0000269|PubMed:15107849, ECO:0000269|PubMed:9426230}.
