Biochemical Activity (Phosphorylation)

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.

Enzymes catalyzing ubiquitination and proteolytic processing of the p105 precursor of nuclear factor kappaB1.

Coux O, Goldberg AL

Nuclear factor kappaB1 (NF-kappaB) is a heterodimeric complex that regulates transcription of many genes involved in immune and inflammatory responses. Its 50-kDa subunit (p50) is generated by the ubiquitin-proteasome pathway from a 105-kDa precursor (p105). We have reconstituted this proteolytic process in HeLa cell extracts and purified the responsible enzymes. Ubiquitination of p105 requires E1, and either of two types ... [more]

Throughput

  • Low Throughput

Additional Notes

  • in vitro ubiquitination with UBA1 as E1, UBCH5B as E2, a purified biochemical fraction that contained an E3 activity named E3kappaB which may correspond to the subsequently cloned KPC1 and NFKB1 as substrate
