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}.

UBA3: inherited and tumour-mutation evidence across 15 cancers

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.

Who runs trials of these drugs

Principal investigators and study chairs on 18 registry trials, updated in the last three years, of the most advanced drugs against UBA3 (pevonedistat), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

14 of 18 trials of drugs against UBA3 have sites only in United States

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.

10 trials of drugs against UBA3 were stopped early; 1 give no reason

Paediatric incentives and obligations for UBA3's drugs

For pevonedistat: what EMA and FDA publish about paediatric plans, orphan status and pediatric approvals, and how many registered studies take children. Each line is a yes, no or not published fact from the record linked under it; none of it is a forecast.

Rare pediatric disease voucher. FDA, content current as of 29 Apr 2026: “As of February 3, 2026, enactment of the Consolidated Appropriations Act, 2026, the rare pediatric disease PRV program will sunset after September 30, 2029. FDA may not award any PRVs under this program after September 30, 2029.” Voucher sale prices are not shown here; they appear only as company-reported news.
