PSMB7 (Proteasome subunit beta type-7) 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.
Component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. This complex plays numerous essential roles within the cell by associating with different regulatory particles. Associated with two 19S regulatory particles, forms the 26S proteasome and thus participates in the ATP-dependent degradation of ubiquitinated proteins.
Open Targets scores its association with cancer at 0.68 (direct and indirect evidence; datatypes literature 0.26, genetic association 0.36, clinical 0.99).

No product in this corpus aims at PSMB7 yet. Inhibitors are shaped to fit the enzyme's active site so the reaction the cancer relies on stops.
Broadly expressed or essential: HPA lists PSMB7 among essential proteins and finds the RNA at low tissue specificity; a medicine acting on the wild-type protein would expose normal tissue too. HPA PSMB7: RNA low tissue specificity; high antibody staining in 32 normal tissues; highest cancer staining testis cancer (11 of 12 high). Distribution: 2 cancer families in the corpus carry a prevalence row, label threshold or catalogue link for it (Multiple myeloma, Lymphoma); Open Targets associates it with 2 specific cancer types at or above 0.5 (plasma cell myeloma, mantle cell lymphoma). (Rule 7 of scripts/fetch-target-specificity.ts.)

Component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. This complex plays numerous essential roles within the cell by associating with different regulatory particles. Associated with two 19S regulatory particles, forms the 26S proteasome and thus participates in the ATP-dependent degradation of ubiquitinated proteins. The 26S proteasome plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins that could impair cellular functions, and by removing proteins whose functions are no longer required. Associated with the PA200 or PA28, the 20S proteasome mediates ubiquitin-independent protein degradation. This type of proteolysis is required in several pathways including spermatogenesis (20S-PA200 complex) or generation of a subset of MHC class I-presented antigenic peptides (20S-PA28 complex). Location: Cytoplasm; Nucleus (UniProt). Locus 9q33.3 (HGNC).
RNA: low tissue specificity, detected in all normal tissues.
Medium: Adipose tissue, Appendix, Bone marrow, Caudate, Duodenum, Hippocampus, Ovary, Skeletal muscle.
Medium only: lymphoma.
