Biochemical Activity (Sumoylation)
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.

MEL-18 interacts with HSF2 and the SUMO E2 UBC9 to inhibit HSF2 sumoylation.
In a previous study we found that sumoylation of the DNA-binding protein heat shock factor 2 (HSF2) is up-regulated during mitosis, but the mechanism that mediates this regulation was unknown. Here we show that HSF2 interacts with the polycomb protein MEL-18, that this interaction decreases during mitosis, and that overexpression and RNA interference-mediated reduction of MEL-18 result in decreased and ...
