PO-B was originally characterized as a transcriptional regulatory factor of the pro-opiomelanocortin (POMC) gene ; however, it has become increasingly clear that this protein may be active in tissues outside the pituitary , since it is present in diverse cell types, including differentiated HL-60 promyelocytic leukemia cells .
