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.

Nedd8-modification of Cul1 is promoted by Roc1 as a Nedd8-E3 ligase and regulates its stability.

Morimoto M, Nishida T, Nagayama Y, Yasuda H

SCF is a ubiquitin ligase and is composed of Skp1, Cul1, F-box protein, and Roc1. The catalytic site of the SCF is the Cul1/Roc1 complex and RING-finger protein Roc1. It was shown earlier that when Cul1 was co-expressed with Roc1 in Sf-9 cells in a baculovirus protein expression system, Cul1 was highly neddylated in the cell, suggesting that Roc1 may ... [more]

Throughput

  • Low Throughput

Additional Notes

  • Autoubiquitination did not require Neddylation of Cul1 (with UbcH5c E2)
  • Autoubiquitination required Neddylation of Cul1 (with Cdc34 E2)
  • Neddylation (with Ubc12 as E2)
  • Ubiquitination (with Cdc34 or UbcH5c as E2)

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.
