Biochemical Activity (Ubiquitination)

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.

Inactivation of VHL by tumorigenic mutations that disrupt dynamic coupling of the pVHL.hypoxia-inducible transcription factor-1alpha complex.

Miller F, Kentsis A, Osman R, Pan ZQ

The von Hippel-Lindau (VHL) gene product, pVHL, targets the alpha subunit of the hypoxia-inducible transcription factor (HIF-alpha) for ubiquitin-dependent degradation. This tumor suppressor function is mediated by the alpha- and beta-domains responsible for assembling the pVHL E3 ubiquitin ligase complex and for recognizing the prolyl-hydroxylated HIF-alpha, respectively. The molecular basis for a large number of tumor-derived mutations can be attributed ... [more]
