TOP2B (DNA topoisomerase 2-beta) 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 Lung cancer, Neuroendocrine tumours, Breast cancer and 1 more. 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.
Biology
Key decatenating enzyme that alters DNA topology by binding to two double-stranded DNA molecules, generating a double-stranded break in one of the strands, passing the intact strand through the broken strand, and religating the broken strand. Plays a role in B-cell differentiation. Location: Nucleus, nucleolus; Nucleus, nucleoplasm; Nucleus (UniProt). Locus 3p24.2 (HGNC).
