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.

Hypoxia inactivates the VHL tumor suppressor through PIASy-mediated SUMO modification.

Cai Q, Verma SC, Kumar P, Ma M, Robertson ES

The hypoxic microenvironment contributes to embryonic development and tumor progression through stabilization of the potent transcriptional factor HIFalpha. In normoxia, the tumor suppressor protein VHL acts as an E3 ubiquitin ligase to target HIFalpha for proteolytic destruction. Increasing evidence shows that VHL is a multifunctional adaptor involved in inhibition of HIFalpha-dependent and independent cellular processes. However, the molecular effect of ... [more]
