OnCo

PAX5 (Paired box protein Pax-5) is a protein that switches other genes on and off. The public catalogues list it as an oncogene driver, a tumour suppressor, a biomarker and a fusion partner, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Non-Hodgkin lymphoma, Leukaemia, Breast cancer and 5 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

Transcription factor that plays an essential role in commitment of lymphoid progenitors to the B-lymphocyte lineage. Fulfills a dual role by repressing B-lineage inappropriate genes and simultaneously activating B-lineage-specific genes. In turn, regulates cell adhesion and migration, induces V(H)-to-D(H)J(H) recombination, facilitates pre-B-cell receptor signalling and promotes development to the mature B-cell stage. Repression of the cohesin-release factor WAPL causes global changes of the chromosomal architecture in pro-B cells to facilitate the generation of a diverse antibody repertoire. Also participates in the inhibition of lytic EBV reactivation by modulating viral BZLF1 activity. Location: Nucleus (UniProt). Locus 9p13.2 (HGNC).
