The molecular events underlying the assembly and maturation of the early pre-60S particles during eukaryotic ribosome synthesis are not well understood. Here, the authors combine yeast genetics and biochemical experiments to characterise the functions of two important players of eukaryotic ribosome biogenesi...
(Fig.6). RNA editing, as a co/posttranscriptional modification, can change nucleotide sequences and have important effects on viral replication, protein synthesis, infection, and virulence. ADARs and APOBECs, in addition to deamination, are RNA-binding proteins that directly interact with endogenous...
? RNase protection studies: Transcripts synthesized by the enzyme are used as precursor RNA for studies on RNA splicing and processing. ? Synthesis of capped RNAin vitrowith addition of m7GpppG or m7GpppA in excess over GTP or ATP during the transcription reaction. The generated antisense RNA ...
RNA modifications are changes to the chemical composition of ribonucleic acid (RNA) molecules post-synthesis that have the potential to alter function or stability. An example of RNA modification is the addition of a methylated guanine nucleotide cap to the 5-end of messenger RNAs (mRN...
