Interferon regulatory factor 4 (IRF4) also known as MUM1 is a protein that in humans is encoded by the IRF4gene.[5][6][7] IRF4 functions as a key regulatory transcription factor in the development of human immune cells.[8][9] The expression of IRF4 is essential for the differentiation of T lymphocytes and B lymphocytes as well as certain myeloid cells.[8] Dysregulation of the IRF4 gene can result in IRF4 functioning either as an oncogene or a tumor-suppressor, depending on the context of the modification.[8]
The MUM1 symbol is also the current HGNC official symbol for melanoma associated antigen (mutated) 1 (HGNC:29641).
