Abstract

Protein modification by the small ubiquitin-related modifier (SUMO) protein regulates numerous cellular pathways and mounting evidence reveals a critical role for SUMO in modulating gene expression. Dynamic sumoylation of transcription factors, chromatin-modifying enzymes, histones, and other chromatin-associated factors significantly affects the transcriptional status of the eukaryotic genome. Recent studies have employed high-throughput ChIP-Seq analyses to gain clues regarding the role of the SUMO pathway in regulating chromatin-based transactions. Indeed, the global distribution of SUMO across chromatin reveals an important function for SUMO in controlling transcription, particularly of genes involved in protein synthesis. These newly appreciated patterns of genome-wide sumoylation will inform more directed studies aimed at analyzing how the dynamics of gene expression are controlled by posttranslational SUMO modification.
