Lagging strand gap suppression connects BRCA-mediated fork protection to nucleosome assembly by ensuring PCNA-dependent CAF-1 recycling

Tanay Thakar, Joshua Straka, Claudia M. Nicolae, George‐Lucian Moldovan

This study identifies lagging strand ssDNA gaps as drivers of fork degradation in BRCA-deficient cells by inhibiting PCNA unloading and CAF-1-dependent nucleosome assembly.
