In the last issue of the Biochemist (the journal of the Biochemical society) is focus on RNA. The different reviews, written by leading RNA scientists, give an overview of the function of ribozymes, novel initiation codons and RNA modifications in RNA biology. In addition, this issue provides an comprehensive description of the mechanisms of RNA silencing in plants, the emergent roles of mitochondrial RNAs and chromosome silencing by Xist non-coding RNA. We have contributed to it with a snapshot in our current knowledge in RNA-binding proteins and the news avenues of research that aroused from the HeLa and HEK293 mRNA interactomes (Castello et al., Cell 2012 and Baltz et al., Mol Cell, 2012).
