WebAug 1, 2024 · Protein SUMOylation is a multistep enzymatic cascade reaction. First, all SUMO paralogues are synthesized as preproteins that are cleaved by SENPs to expose a carboxy-terminal diglycine (GG) motif. An ATP-requiring activation step by the heterodimeric SUMO E1 generates a SUMO-SUMO E1 thioester. WebSmall ubiquitin-related modifier (SUMO) is an ubiquitin-like protein that is covalently attached to a variety of target proteins. Unlike ubiquitination, sumoylation does not target proteins for proteolytic breakdown, but is involved in regulation of protein function, nuclear targeting, and the formation of subcellular structures.
