MDM4 MDM4 regulator of p53

ENSG00000198625 · protein coding · Open Targets profile

Contributes to p53/TP53 regulation (PubMed:32300648). Inhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding their transcriptional activation domains. Inhibits degradation of MDM2. Can reverse MDM2-targeted degradation of TP53 while maintaining suppression of TP53 transactivation and apoptotic functions. {ECO:0000269|PubMed:16163388, ECO:0000269|PubMed:16511572, ECO:0000269|PubMed:32300648}.

In 9 of 15 cancers, the evidence for MDM4 comes mainly from mutations found in tumours

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 0.033229000866413116 (upper bound 0.10459999740123749). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of MDM4's approved or late-stage drugs in the last three years.

No terminated, withdrawn or suspended trials of MDM4's drugs are registered
