Biochemical Activity (Deacetylation)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Acetylation of SUMO2 at lysine 11 favors the formation of non-canonical SUMO chains.

Gaertner A, Wagner K, Hoelper S, Kunz K, Rodriguez MS, Mueller S

Post-translational modifications by ubiquitin-related SUMO modifiers regulate cellular signaling networks and protein homeostasis. While SUMO1 is mainly conjugated to proteins as a monomer, SUMO2/3 can form polymeric chains. Poly-SUMOylation is best understood in the SUMO-targeted ubiquitin ligase (StUbL) pathway, where chains prime proteins for subsequent ubiquitylation by StUbLs. SUMO chains typically form in response to genotoxic or proteotoxic stress and ... [more]
