S-adenosyl-L-methionine-dependent methyltransferase which methylates the carbon-5 position of cytosine 2381 to 5-methylcytosine (m5C2381) in 26S rRNA (Schosserer et al. 2015,
Heissenberger et al. 2020 ,
Navarro et al. 2021 ).
Plays a role in the production of mature 5S, 5.8S, 18S and 26S rRNAs and promotes the processing of the internally transcribed spacer 2 (ITS2), which separates the 5.8S and 26S rRNAs on large pre-rRNA precursors (Heissenberger et al. 2020 ,).
Methylation of ribosomal RNA by NSUN5 is a conserved mechanism modulating organismal lifespan.
