Abstract
Chromatin signaling events are critical for the dynamic regulation of the genome. Although much has been learned about histone modification in these events, the modification of nonhistone chromatin regulators and cross-talk between these pathways is less well understood. Here, Appikonda et al. demonstrate that the transcription co-factor and oncoprotein TRIM24 (tripartite motif-containing protein 24) is SUMOylated upon association with a specific histone modification signature, which regulates the transcription of genes involved in cell adhesion. These data extend our understanding of signaling cascades in the nucleus and offer new insights for cancer drug development.
