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

Function

MN1 is a transcription coregulator that enhances or represses RAR/RXR-mediated gene transcription through interaction with RAC3 and p300.[2] MN1 also acts as a coactivator of the vitamin D receptor.[3]

Clinical significance

Its inactivation may be part of the cause of certain meningiomas.[1] A potential link to leukemia[4] including acute myeloid leukemia[5] has also been described.
