A genome-scale adaptation map identifies the FANCM-RMI1/2 complex as an opposing modulator of cell fitness upon BRCA1 or BRCA2 loss.
Cancer cells lacking BRCA1 or BRCA2 must adapt to proliferate despite pervasive genomic instability. To delineate BRCA1- and BRCA2-specific adaptation landscapes, we developed an isogenic screening platform enabling acute depletion of either protein. Genetic interaction profiling revealed hundreds of genes with shared,...
