The cell's protein shredder. Myeloma cells make huge amounts of antibody protein and depend on the proteasome to clear the waste, so blocking it kills them. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Multi-subunit protease complex that degrades ubiquitinated proteins; PSMB5 carries the chymotrypsin-like catalytic activity targeted by approved inhibitors.
| Cancer | Prevalence | Measure | Note | Source |
|---|---|---|---|---|
| Metastatic cancer | all% | Housekeeping enzyme present in every dividing cell (protein disposal, on which myeloma cells depend most); not a selection marker, which is why these drugs are given by cancer type rather than by test. |
