UBR5 is a modulator of MYC stability. (A) Gene enrichment score in high GFP/mCHERRY-sorted cells relative to unsorted cell population on day 7 of library infection visualized as LogFC. (B) sgRNA-mediated knockout of UBR5 (sgUBR5), FBXW7 (sgFBXW7) or a non-targeting sgRNA control (sgNT) in B6 clone and analysis of GFP, mCHERRY, and GFP/mCHERRY ratio using FACS 7 days post-knockout. (C) MYC degradation screen using an arrayed sgRNA sublibrary. MYC-GFP/mCHERRY cells were infected with lentiviruses encoding for sgRNAs targeting HECT E3 ligases. 2 sgRNAs were used per gene (indicated as 1, 2). Seven days after infection and selection with puyromycin, GFP/mCHERRY was measured using flow cytometry and the increase in GFP/mCHERRY ratio upon knockout of the singlegenes was compared to a non-targeting control (sgNT).
