Deciphering arginine methylation: Tudor tells the tale

Abstract: Proteins can be modified by post-translational modifications such as phosphorylation, methylation, acetylation and ubiquitylation, creating binding sites for specific protein domains. Methylation has pivotal roles in the formation of complexes that are involved in cellular regulation, including in the generation of small RNAs. Arginine methylation was discovered half a century ago, but the ability of methylarginine sites to serve as binding motifs for members of the Tudor protein family, and the functional sig… Show more

“…Reversible post-translational modification of proteins, often regulated by enzymes that add ('writers') or remove ('erasers') moieties to individual amino acids, allows rapid changes in interaction with other proteins ('readers') that recognise the modifications [32]. Such modifications include phosphorylation, acetylation, sumoylation, ubiquitylation, methylation and poly(ADP-ribosyl)ation ('PARylation'), all of which have been detected in SAFB proteins.…”

“…A variety of RNA-binding proteins involved in RNA metabolism contain RGG motifs. 21 Consistent with this observation, RGG motifs have emerged as key players in orchestrating post-transcriptional gene regulation. This review explores and hypothesizes functional significance of RGG motifs in mRNA translation/ decay and its regulation through arginine methylation.…”

“…23,24 Arginine methylation is probably most important in modulating RNA biogenesis and function, since RNA binding proteins form the largest group of arginine methylated proteins. 21 Arginine methylation can have either positive or negative effects on protein-protein or protein-RNA interactions. In a straightforward example, purified methylated HuD binds weakly to target p21 mRNA as compared with unmethylated HuD.…”

“…Post-translational methylation of Piwi arginine residues near the protein's N-terminus allow Piwi to be recognized by a suite of Tudor domain-containing proteins. These Tudor proteins are believed to serve as localization and scaffolding molecules which tether piRNA components together (reviewed in [116]). Alternatively, if Piwi is translocated to the nucleus, factors including Maelstrom and chromatin modifiers are recruited to genomic loci to establish hetrochromatic silencing marks (Box 2).…”
