DDR2 discoidin domain receptor tyrosine kinase 2

ENSG00000162733 · protein coding · Open Targets profile

Tyrosine kinase involved in the regulation of tissues remodeling (PubMed:30449416). It functions as a cell surface receptor for fibrillar collagen and regulates cell differentiation, remodeling of the extracellular matrix, cell migration and cell proliferation. Required for normal bone development. Regulates osteoblast differentiation and chondrocyte maturation via a signaling pathway that involves MAP kinases and leads to the activation of the transcription factor RUNX2. Regulates remodeling of the extracellular matrix by up- regulation of the collagenases MMP1, MMP2 and MMP13, and thereby facilitates cell migration and tumor cell invasion. Promotes fibroblast migration and proliferation, and thereby contributes to cutaneous wound healing. {ECO:0000269|PubMed:16186104, ECO:0000269|PubMed:16186108, ECO:0000269|PubMed:17665456, ECO:0000269|PubMed:18201965, ECO:0000269|PubMed:20004161, ECO:0000269|PubMed:20564243, ECO:0000269|PubMed:20734453, ECO:0000269|PubMed:30449416, ECO:0000269|PubMed:9659899}.

In 12 of 15 cancers, the evidence for DDR2 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 0.2845599949359894 (upper bound 0.3924199938774109). 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 179 registry trials, updated in the last three years, of the most advanced drugs against DDR2 (regorafenib), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

53 of 163 trials of drugs against DDR2 have sites only in China

Registry trials of regorafenib 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; 137 of 163 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. 16 trials list no sites and are left out. Source: ClinicalTrials.gov, fetched live.
