ARAF A-Raf proto-oncogene, serine/threonine kinase

ENSG00000078061 · protein coding · Open Targets profile

Involved in the transduction of mitogenic signals from the cell membrane to the nucleus. May also regulate the TOR signaling cascade. Phosphorylates PFKFB2 (PubMed:36402789). .

1 of the 3 drugs recorded against ARAF is approved

Each band is a group of drugs. It runs from the kind of drug on the left to the furthest stage that drug has reached in any disease on the right. Thicker bands mean more drugs.

Approved bands are highlighted. Withdrawn means the drug was pulled from the market or from development. A combined phase counts as the later one (Phase 1/2 is shown as Phase 2). Hover a band for the drug names. Source: Open Targets Platform, fetched live.

In 13 of 15 cancers, the evidence for ARAF 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.

gnomAD loss of function constraint: o/e 0.37474000453948975 (upper bound 0.5556899905204773). 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 17 registry trials, updated in the last three years, of the most advanced drugs against ARAF (tovorafenib, belvarafenib), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

3 of 15 trials of drugs against ARAF have sites only in United States

Registry trials of tovorafenib, belvarafenib 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; 7 of 15 have all sites in one country.
