    Recruitment of 53BP1 to double-strand DNA breaks is an important step in the cellular response to DNA damage. Here, the histone methyltransferase MMSET is shown to be responsible for localized increases in a histone modification that is involved in recruiting 53BP1. The mechanism of MMSET recruitment to DNA damage sites is also investigated.

    Various biological processes are entrained by the day–night cycle to occur at a specific time of day. One way the circadian system exerts these effects is through post-transcriptional regulation. These authors show that a protein that transfers methyl groups onto several spliceosome subunits, PRMT5, is regulated by the light–dark cycle. Methylation of these subunits affects alternative splicing of some genes, thus making them subject to circadian control.

    α-N-methylation is an unusual post-translational modification in which the amino-terminal residues of proteins are methylated. One example is the Ran guanine nucleotide-exchange factor, RCC1, which requires methylation for its association with chromatin. These authors describe the first α-N-methyltransferase, named N-terminal RCC1 methyltransferase (NRMT). They identify the NRMT recognition sequence and several new methylation targets, and demonstrate the importance of α-N-methylation for normal bipolar spindle formation and chromosome segregation.
