This database lists the “hits” from a kinome-wide CRISPR knockout screen to identify protein kinases that regulate vasopressin-dependent Aqp2 gene transcription in a polarized mouse renal collecting duct cell line (mpkCCD). The screen utilized Cas9-expressing mpkCCD cells featuring a GFP-reporter inserted at the 5’ end of the Aqp2 gene allowing it to be co-transcribed with Aqp2. The cells were grown on permeable supports and treated with a vasopressin V2 receptor-selective analog (dDAVP). A lentiviral kinome library, targeting 713 kinase and kinase-related genes (n=4 guide RNAs per target), was introduced at low multiplicity of infection (MOI ≈0.1). The cells were sorted into populations based on their GFP fluorescence intensity using FACS. The genomic DNA was then extracted, and guide RNA counts were derived for each faction using Next-Generation Sequencing (NGS). Computational analysis using MAGeCK (https://sourceforge.net/p/mageck/wiki/Home/) identified kinases whose deletion significantly enriched (negative regulators) or depleted (positive regulators) particular guide RNAs in the high- versus low-GFP populations.
Database was created by Euijung Park, Lihe Chen, and Mark Knepper in the Epithelial Systems Biology Laboratory (Mark Knepper, Chief) at the National Heart, Lung and Blood Institute as part of its Kidney Systems Biology Project. Reference: Pending. Click to download processed data as spreadsheet.
