27437582 using dual- and quadruple-trap optical tweezers combined with fluorescence microscopy, we show how human XRCC4, XLF and XRCC4-XLF complexes interact with DNA in real time
26100018 The data suggest that XLF has multiple functions in DNA repair, and they offer potential explanations for the pleiotropic phenotypes associated with XLF deficiency.
25661488 Phosphorylation of XLF impairs non-homologous end-joining DNA repair.
25321468 PC4 protects esophageal squamous cell carcinoma cells from IR-induced death by enhancing the nonhomologous end joining-promoting activity of XLF.
24626809 Werner syndrome protein positively regulates XRCC4-like factor transcription.
24461734 Human XLF is a non-essential, but critical, classic non-homologous end-joining -repair factor.
23818183 An induced pluripotent stem cell (iPSC) model of XLF deficiency, which accurately replicates the double-strand break repair deficiency observed in XLF syndrome patients, is reported.
23620595 Data indicate that Ku70/Ku80 facilitates the cooperative binding of multiple XRCC4/Ligase IV (XL) and XLF molecules to DNA.
23442139 XRCC4 and XLF form long helical protein filaments suitable for DNA end protection and alignment to facilitate DNA double strand break repair. (Review)
23207905 Cernunnos deficiency results in chronic activation of the DNA damage response, P53-driven upregulation of proapoptotic factors, leading to decreased thymocyte viability and a qualitative alteration of the T cell repertoire in both humans and mice.
