Defective Inhibition of DNA Recombination at Telomere Due to ATRX Mutations
Click the image above or here to open this pathway in the Pathway Browser
Many tumors that are positive for markers of alternative lengthening of telomeres (ALT) harbor loss-of-function mutations in the ATRX gene, encoding a chromatin remodeling protein ATRX. ATRX is thought to act together with DAXX and histone H3F3A to inhibit DNA recombination at telomere ends. For review, please refer to Heaphy et al. 2011, Gocha et al. 2014, Pickett and Reddel 2015, Amorim et al. 2016.
