Fig. 3. ICS detects the effects of CRISPR perturbations and enables
pooled genetic screens of protein localization.(A) Effects of individual
CRISPR perturbations on RelA nuclear translocation. HeLa cells with Tet-
inducible Cas9 and stably expressing RelA-mNG were transduced with gRNA-1,
gRNA-2, and gRNA-3 targeting the core NF-kB pathway proteins IKBKG, IKBKA,
and MAP3K6, respectively, or with nontargeting (nt) control gRNAs. gRNA
expression was induced with doxycycline (Dox) or left uninduced. Correlation
between RelA-mNG and DRAQ5 was quantified using ICS as a measurement for
RelA nuclear translocation in the presence or absence of TNFa.(B) Overview
of the pooled CRISPR screening setup and readout using ICS. Positive regulators
of RelA nuclear translocation are enriched in the lower bin and depleted from
the upper bin. Tet::Cas9, tetracycline/doxycycline–inducible Cas9. (CtoE) Results


of the ICS-based CRISPR screen using an NF-kB pathway–focused library (n=
1068 genes). (C) The screen was performed at different library coverages,
and reads from collected samples were combined in silico to a high-coverage
(359 cells per gRNA per sorted bin) dataset. Hits were called using the software
MAUDE ( 26 ). Genes are ranked by their statistical significance and selected
positive/negative regulators are highlighted. The horizontal dashed lines indicate
an FDR of 1%, whereas genes with FDR <1% are marked in cyan and orange,
respectively. (D) Comparison of phenotypes measured in individual perturbation
experiments from (A) (xaxis) or the pooled screen (yaxis) using the same
gRNAs. For the pooled screen, differences in gRNA abundance in the upper (top
panel) and lower (bottom panel) sorted bins compared with the input sample
were determined from the high-coverage dataset in (C).Rvalues represent
