Gene: NSUN2 (NOP2/Sun RNA methyltransferase 2) Homo sapiens
Symbol: NSUN2
Name: NOP2/Sun RNA methyltransferase 2
Description: Exhibits mRNA (cytidine-5-)-methyltransferase activity and tRNA (cytosine-5-)-methyltransferase activity. Involved in mRNA methylation; regulation of mRNA export from nucleus; and tRNA methylation. Localizes to the extracellular exosome; mitochondrion; and nucleolus. Implicated in autosomal recessive non-syndromic intellectual disability.
Type: protein-coding
RefSeq Status: REVIEWED
