NSUN2 (Q08J23) - Overview - Molecular Target Synopsis


NSUN2, tRNA (cytosine(34)-C(5))-methyltransferase
Enzyme Classification
UniProt Q08J23

Also Known as NSUN2_HUMAN, NSUN2, SAKI, TRM4

RNA methyltransferase that methylates tRNAs, and possibly RNA polymerase III transcripts. Methylates cytosine to 5-methylcytosine (m5C) at positions 34 and 48 of intron-containing tRNA(Leu)(CAA) precursors, and at positions 48, 49 and 50 of tRNA(Gly)(GCC) precursors. May act downstream of Myc to regulate epidermal cell growth and proliferation. Required for proper spindle assembly and chromosome segregation, independently of its methyltransferase activity. Interacts with NPM1 and NCL during interphase; interaction is disrupted following phosphorylation at Ser-139.
