Interferon regulatory factor 4 also known as MUM1 is a protein that in humans is encoded by the IRF4 gene, located at 6p25-p23.

The MUM1 symbol is polysemous; although it is an older synonym for IRF4 (HGNC:6119), it is also the current HGNC official symbol for melanoma associated antigen (mutated) 1 (HGNC:29641; located at 19p13.3).

Clinical significance

In melanocytic cells the IRF4 gene may be regulated by MITF. IRF4 is a transcription factor that has been implicated in acute leukemia. This gene is strongly associated with pigmentation: sensitivity of skin to sun exposure, freckles, blue eyes, and brown hair color. A variant has been implicated in greying of hair.

Interactions

IRF4 has been shown to interact with:

• BCL6,
• NFATC2,
• SPI1, and
• STAT6.
