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.

Oncogenic Ras abrogates MEK SUMOylation that suppresses the ERK pathway and cell transformation.

Kubota Y, O'Grady P, Saito H, Takekawa M

The ERK (extracellular signal-regulated kinase) MAPK (mitogen-activated protein kinase) cascade (Raf-MEK-ERK) mediates mitogenic signalling, and is frequently hyperactivated by Ras oncogenes in human cancer. The entire range of activities of multifunctional Ras in carcinogenesis remains elusive. Here we report that the ERK pathway is downregulated by MEK (MAPK-ERK kinase) SUMOylation, which is inhibited by oncogenic Ras. MEK SUMOylation blocked ERK ... [more]
