POLQ (DNA polymerase theta) is an enzyme. The public catalogues list it as an oncogene driver, a tumour suppressor and a DNA repair gene, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Lung cancer, Endometrial cancer, 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.
Low-fidelity DNA polymerase with a putative helicase activity that promotes microhomology-mediated end-joining (MMEJ), an alternative non-homologous end-joining (NHEJ) machinery required to repair double-strand breaks in DNA during mitosis. MMEJ is an error-prone repair pathway that produces deletions of sequences from the strand being repaired and promotes genomic rearrangements, such as telomere fusions, some of them leading to cellular transformation. MMEJ is required during mitosis to repair persistent double-strand breaks that originate in S-phase. Although error-prone, MMEJ protects against chromosomal instability and tumorigenesis. The polymerase acts by binding directly the 2 ends of resected double-strand breaks, allowing microhomologous sequences in the overhangs to form base pairs. It then extends each strand from the base-paired region using the opposing overhang as a template. Location: Nucleus; Chromosome (UniProt). Locus 3q13.33 (HGNC).
