Myelin Regulatory Factor (MRF), also known as Myelin regulatory factor, MYRF, and encoded by the gene MYRF/C11orf9/KIAA0954/MRF, is an interesting protein that gets cleaved into two chains. The N terminal component specifically activates transcription of myelin gene in the CNS oligodendrocytes and pre-oligodendrocytes. The C-terminal portion, which is remains membrane bound, appears to play no role in gene induction but its complete role is still being discovered. The N-terminal portion of MRF activates MBP, MOG, MAG, and PLP among other genes, but it is not required for oligodendrocyte differentiation but is required for the maintenance of myelin in the adult. MRF whole factor is localized to the endoplasmic reticulum. The cleaved N terminal portion translocates to the nucleus and the C-terminal portion remains in the endoplasmic reticulum. Interestingly MRF can be found expressed outside of oligodendrocytes and oligo precursors in the brain including regions such as the lung, basal ganglion and liver.
