UBA3 ubiquitin like modifier activating enzyme 3
ENSG00000144744 · protein coding · Open Targets profile
Catalytic subunit of the dimeric UBA3-NAE1 E1 enzyme. E1 activates NEDD8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a NEDD8-UBA3 thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of UBE2M. Down- regulates steroid receptor activity. Necessary for cell cycle progression. {ECO:0000269|PubMed:10207026, ECO:0000269|PubMed:12740388, ECO:0000269|PubMed:9694792}.
Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.
Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.35394999384880066 (upper bound 0.49112001061439514). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Registry trials of pevonedistat updated in the last three years, counted by the country group of their listed sites. A trial with sites in several groups counts in each; 15 of 18 have all sites in one country.
Site counts are not patients per country, and trials registered only outside ClinicalTrials.gov are not covered. Where sites are is a fact about the record, not a judgement of its quality. Europe is the EU and EEA, the UK and Switzerland. Source: ClinicalTrials.gov, fetched live.
