RrmJ-type ribose 2-O-methyltransferase domain (IPR025816)

Short name: RrmJ-type_MeTrfase

Overlapping homologous superfamilies

Domain relationships


This domain is found in cap-specific mRNA (nucleoside-2-O-)-methyltransferase 1, which is a S-adenosyl-L-methionine-dependent methyltransferase that mediates mRNA cap1 2'-O-ribose methylation to the 5'-cap structure of mRNAs [PMID: 20713356]. It methylates the ribose of the first nucleotide of a m7GpppG-capped mRNA to produce m7GpppNmp (cap1). Cap1 modification is linked to higher levels of translation. It may be involved in the interferon response pathway [PMID: 18533109]. This group also includes A8XYX3, which is thought to be inactive as it lacks the conserved Lys active site in position 367.
