Functional analysis of Kap1 genomic recruitment

A current model for the genomic recruitment of Kap1 is via its interaction with KRAB domain-containing zinc finger transcription factors. We have performed ChIP-seq for various mutant KAP1 proteins and shown that this recruitment mechanism mediates binding of KAP1 only to the 3’ ends of zinc finger genes and that other factors are involved in recruiting KAP1 to promoter regions. 17 total ChIP-seq datasets; three different FLAG-KAP1 mutants, one FLAG-KAP1 wild type, and four different Input datasets from 4 different stable cell lines derived from HEK293 cells: 1 FLAG-KAP1 wild type dataset and 1 Input dataset done from HEK293 stable cells; 1 FLAG-KAP1 HP1BDmut dataset and 1 Input dataset done from HEK293 stable cells, 1 FLAG-KAP1 N-ter RBCC{delta}mut dataset and 1 Input dataset done from HEK293 stable cells, 1 FLAG-KAP1 C-ter PB{delta}mut dataset and 1 Input dataset done from HEK293 stable cells. One FLAG-KAP1 N/C-ter (RBCC+PB){delta}mut dataset done from T-REx HEK293 stable cells. One endogenous KAP1 dataset done from HEK293 cells. Two independent ELK4 datasets done from duplicate HEK293 cells. One endogenous Kap1 dataset and one Input dataset from a stable cell line derived from U2OS cells.
