Target Background

ATP-dependent DNA helicase implicated in telomere-length regulation, DNA repair and the maintenance of genomic stability. Acts as an anti-recombinase to counteract toxic recombination and limit crossover during meiosis. Regulates meiotic recombination and crossover homeostasis by physically dissociating strand invasion events and thereby promotes noncrossover repair by meiotic synthesis dependent strand annealing (SDSA) as well as disassembly of D loop recombination intermediates. Also disassembles T loops and prevents telomere fragility by counteracting telomeric G4-DNA structures, which together ensure the dynamics and stability of the telomere.

Pulmonary fibrosis patients with mutations in telomerase reverse transcriptase, telomerase RNA component, regulator of telomere elongation helicase 1 and poly(A)-specific ribonuclease were identified and clinical data were analysed.

  12. Heterozygous RTEL1 mutations are responsible for familial pulmonary fibrosis (FPF) and, thereby, extend the clinical spectrum of RTEL1 deficiency. Thus, RTEL1 enlarges the number of telomere-associated genes implicated in FPF. PMID: 26022962
