CD74 CD74 molecule

ENSG00000019582 · protein coding · Open Targets profile

Plays a critical role in MHC class II antigen processing by stabilizing peptide-free class II alpha/beta heterodimers in a complex soon after their synthesis and directing transport of the complex from the endoplasmic reticulum to the endosomal/lysosomal system where the antigen processing and binding of antigenic peptides to MHC class II takes place. Serves as cell surface receptor for the cytokine MIF.

1 of the 2 drugs recorded against CD74 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 Withdrawn means the drug was pulled from the market or from development.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 15 of 15 cancers, the evidence for CD74 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 0.5391200184822083 (upper bound 0.7833899855613708). 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 13 registry trials, updated in the last three years, of the most advanced drugs against CD74 (repotrectinib), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

6 of 13 trials of drugs against CD74 have sites only in United States

Registry trials of repotrectinib 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; 8 of 13 have all sites in one country.
