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.

A site-directed mutagenesis study of the MdmX RING domain.

Egorova O, Sheng Y

Mdm2 and MdmX are important negative regulators of the tumor suppressor p53. Structurally homologous Mdm2 and MdmX inhibit p53 by directly blocking p53 transcriptional activation. Mdm2 also modifies and targets p53 for 26S proteasome dependent protein degradation through E3 ligase activity mediated by its C-terminal RING domain. However, MdmX lacks intrinsic E3 ligase activity and fails to catalyze ubiquitination of ... [more]
