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.

Tuning BRCA1 and BARD1 activity to investigate RING ubiquitin ligase mechanisms.

Stewart MD, Duncan ED, Coronado E, DaRosa PA, Pruneda JN, Brzovic PS, Klevit RE

The tumor-suppressor protein BRCA1 works with BARD1 to catalyze the transfer of ubiquitin onto protein substrates. The N-terminal regions of BRCA1 and BARD1 that contain their RING domains are responsible for dimerization and ubiquitin ligase activity. This activity is a common feature among hundreds of human RING domain-containing proteins. RING domains bind and activate E2 ubiquitin-conjugating enzymes to promote ubiquitin ... [more]
