Protein existence	Evidence at protein level

General annotation (Comments)

Function	Transcription regulator required for expression of CNS myelin genes such as Mbp, Mog, Mag and Plp1 thereby playing a central role in oligodendrocyte maturation and central nervous system (CNS) myelination. It is not only required during oligodendrocyte differentiation but is also required on an ongoing basis for the maintenance of expression of myelin genes and for the maintenance of a mature, viable oligodendrocyte phenotype By similarity.
Subcellular location	Membrane; Single-pass membrane protein Potential. Nucleus By similarity.
Tissue specificity	Expressed in lung, ARPE-19 cell line, brainstem, uterus and, to a lesser extent, in basal ganglion and liver. Weakly expressed in cerebellum and retina. Ref.1
Domain	A transmembrane region is predicted by sequence analysis tools. However, the protein is nuclear and probably acts as a transcription factor. It is therefore unclear whether the predicted transmembrane region is a hydrophobic region that does not insert into membranes or whether it is a real transmembrane region that may be cleaved when acting as transcription regulator.
Sequence similarities	Belongs to the MRF family. Contains 1 NDT80 DNA-binding domain.
Sequence caution	The sequence BAA76798.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
