What is the #molecular basis of #syntheticlethality between loss of Werner #helicase #WRN and #mismatchrepair #MMR proteins particularly in #cancer cells with #microsatellite instability?
Using #biochemcial assays, Petr Cejka and colleages, Bellinzona LRB, show how they synergistically and independently unfold #cruciform #DNA structures, with WRN preventing their cleavage by #SLX1-#SLX4 structure-specific #endonuclease and DNA breakage
