TissueNA
Tissue SpecificityExpressed in the promyelocytic cell line HL-60, the granulocyte-macrophage colony-stimulating factor-dependent leukemic cell line F-36P, and the IL3 and erythropoietin-dependent leukemic cell line F-36E. Expressed predominantly in epithelial cells and lymphocytes. Enhanced expression at high cell density. {ECO:0000269|PubMed:12370829, ECO:0000269|PubMed:8483328, ECO:0000269|PubMed:9531590}.
