MN1 is a gene found on human chromosome 22, with gene map locus 22q12.3-qter.[5] Its official full name is meningioma (disrupted in balanced translocation) 1 because it is disrupted by a balanced translocation (4;22) in a meningioma.


MN1 is a transcription coregulator that enhances or represses RAR/RXR-mediated gene transcription through interaction with RAC3 and p300.[6] MN1 also acts as a coactivator of the vitamin D receptor.[7]

Clinical significance[edit]

Its inactivation may be part of the cause of certain meningiomas.[5] A potential link to leukemia[8] including acute myeloid leukemia[9] has also been described.
