ABSTRACT
Gene transcription is intimately linked to chromatin state and histone modifications. However, the enzymes mediating these post-translational modifications have many additional, nonhistone substrates, making it difficult to ascribe the most relevant modification. In this issue of Genes & Development, Crain and colleagues (doi10.1101/gad.351698.124) have combined a powerful histone replacement system with mutational analysis of a chromatin regulator and a chromatin reader in Drosophila melanogaster Importantly, they discovered that genes controlled by the histone 4 lysine 20 (H4K20) methyltransferase Set8 and the protein recognizing H4K20 monomethylation, L(3)mbt, differ substantially from those affected by mutation of H4K20 itself. This demonstrates that H4K20 is not the key substrate for Set8 but that methylation of other, unidentified proteins mediates its effects on transcription.
