GeneID: 267


Common Name: MRM2 Type: Gene
Chromosome: 7 (NC_000007.14) Locus: NM_013393.3 (MRM2)
HUGO Symbol: MRM2 Full Name: mitochondrial rRNA methyltransferase 2
Exons: 3 Introns: 2

MRM2 encodes a nucleolar protein containing a methyltransferase domain. It belongs to S-adenosyl-L-methionine-dependent 2'-O-methyltransferases with a role in the processing and modification of rRNA, a crucial component of ribosome structure and function. MRM2 is suggested to be involved in cell cycle control and DNA repair. It is an ortholog of E.coli RrmJ, a methyltransferase that functions as a heat shock protein. Methylation is important in the regulation of cellular response to stress-stimuli, including drugs. Studies have reported methyltransferase-mediated chromatin structures that modulate azacitidine response/resistance in leukemia cells. Azacitidine is a DNA hypomethylating agent of clinical importance for the treatment of thalassaemia and sickle cell disease (SCD) via induction of Hb F production. A variation in MRM2 was associated with Hb F response to hydroxyurea in SCD cohorts.
