UBR5 (E3 ubiquitin-protein ligase UBR5) is an enzyme. The public catalogues list it as an oncogene driver, a tumour suppressor, a biomarker and a DNA repair gene, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Gastric & gastro-oesophageal junction cancer, Breast cancer, Renal cell carcinoma 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
E3 ubiquitin-protein ligase involved in different protein quality control pathways in the cytoplasm and nucleus. Mainly acts as a ubiquitin chain elongator that extends pre-ubiquitinated substrates. Component of the N-end rule pathway: ubiquitinates proteins bearing specific N-terminal residues that are destabilising according to the N-end rule, leading to their degradation. Recognises type-1 N-degrons, containing positively charged amino acids (Arg, Lys and His). Together with UBR4, part of a cytoplasm protein quality control pathway that prevents protein aggregation by catalysing assembly of heterotypic 'Lys-11'-/'Lys-48'-linked branched ubiquitin chains on aggregated proteins, leading to substrate recognition by the segregase p97/VCP and degradation by the proteasome: UBR5 is probably branching multiple 'Lys-48'-linked chains of substrates initially modified with mixed conjugates by UBR4. Together with ITCH, catalyses 'Lys-48'-/'Lys-63'-branched ubiquitination of TXNIP, leading to its degradation: UBR5 mediates branching of 'Lys-48'-linked chains of substrates initially modified with 'Lys-63'-linked conjugates by ITCH. Location: Nucleus; Cytoplasm (UniProt). Locus 8q22.3 (HGNC).
