From: The role of m6A, m5C and Ψ RNA modifications in cancer: Novel therapeutic opportunities
Molecular mechanism of m5C deposition in RNA, biological function implication in human cancer. a-d m5C RNA deposition landscape in mRNA (a), tRNA (b), rRNA (d), and ncRNAs (c) mediated by writers (blue balloons) NSUN2–6, DNMT2 and NOP2, erasers (pink balloons) TET and ALKBH1, and reader proteins (yellow balloons) YBX1 and AlyREF, and their role in mRNA metabolism. e-h Aberrant m5C deposition in RNAs promotes or suppresses tumour progression through NSUN2 upregulation in mRNA, miRNA and lncRNA (e), NSUN2 downregulation in tRNA (f), NOP upregulation in rRNA (g) or NSUN5 downregulation in rRNA (h). Red arrows indicate induction. Blue arrows with flat end represent inhibition
