PSMB9
PSMB9 (Proteasome subunit beta type-9) is an enzyme. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Multiple myeloma, Non-Hodgkin lymphoma and Mantle cell lymphoma.
Overview
The proteasome is a multicatalytic proteinase complex which is characterised by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides.
Open Targets scores its association with cancer at 0.63 (direct and indirect evidence; datatypes literature 0.96, genetic association 0.00, clinical 0.99).

- 3 · How drugs use it
No product in this corpus aims at PSMB9 yet. Inhibitors are shaped to fit the enzyme's active site so the reaction the cancer relies on stops.

Biology
The proteasome is a multicatalytic proteinase complex which is characterised by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues. Location: Cytoplasm; Nucleus (UniProt). Locus 6p21.32 (HGNC).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: Open Targets known-drug datatype score 0.99. Evidence tier "approved-drug" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
