dc.description.abstract | tRNAs are subject to numerous modifications, including methylation. Mutations in the human N-7-methylguanosine (m(7)G) methyltransferase complex METTL1/WDR4 cause primordial dwarfism and brain malformation, yet the molecular and cellular function in mammals is not well understood. We developed m(7)G methylated tRNA immunoprecipitation sequencing (MeRIP-seq) and tRNA reduction and cleavage sequencing (TRAC-seq) to reveal the m(7)G tRNA methylome in mouse embryonic stem cells (mESCs).A subset of 22 tRNAs is modified at a ''RAGGU'' motif within the variable loop. We observe increased ribosome occupancy at the corresponding codons in Mettl1 knockout mESCs, implying widespread effects on tRNA function, ribosome pausing, and mRNA translation. Translation of cell cycle genes and those associated with brain abnormalities is particularly affected. Mettl1 or Wdr4 knockout mESCs display defective self-renewal and neural differentiation. Our study uncovers the complexity of the mammalian m(7)G tRNA methylome and highlights its essential role in ESCs with links to human disease. | - |
