Chemogenetic ubiquitin E1 inhibitor TAK-243 CRISPR screen uncovers HAPSTR1/HUWE1 axis in chromatin proteostasis and cell cycle control

In this study, we sought to comprehensively map ubiquitin signaling networks at the crossroads of cellular proliferation and proteostasis, both crucial in cancer. Genome-wide CRISPR knockout screening in the presence of the ubiquitin E1 inhibitor TAK-243 identified 239 genes whose ablation sensitizes cells to ubiquitin...
