GIPR gastric inhibitory polypeptide receptor
ENSG00000010310 · protein coding · Open Targets profile
This is a receptor for GIP. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. .
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 Withdrawn means the drug was pulled from the market or from development.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.
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 1.1904000043869019 (upper bound 1.4443999528884888). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Registry trials of tirzepatide, retatrutide 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; 177 of 238 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. 17 trials list no sites and are left out. Source: ClinicalTrials.gov, fetched live.
