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.

Comparison of substrate specificity of the ubiquitin ligases Nedd4 and Nedd4-2 using proteome arrays.

Target recognition by the ubiquitin system is mediated by E3 ubiquitin ligases. Nedd4 family members are E3 ligases comprised of a C2 domain, 2-4 WW domains that bind PY motifs (L/PPxY) and a ubiquitin ligase HECT domain. The nine Nedd4 family proteins in mammals include two close relatives: Nedd4 (Nedd4-1) and Nedd4L (Nedd4-2), but their global substrate recognition or differences ... [more]

Throughput

  • High Throughput

Additional Notes

  • High Throughput: A ubiquitination assay was applied to a protein microarray in order to identify substrates of the E3 enzyme Nedd4. The reaction contained E1, UbcH5b [E2], and FITC-labelled ubiquitin.
  • High Throughput: Only those proteins that showed four independent interactions were considered substrates (i.e. significant signals found for proteins printed in duplicate on two separate microarrays). The top ~50 hits were selected as high-confidence data sets.
