NFKB1 and infection: Previous studies have successfully identified ASB from ChIP-seq for all NF-κB subunits in LCLs (Martone et al. 2003; Lim et al. 2007; Heinz et al. 2010; Kasowski et al. 2010; Zhao et al. 2014; Jin et al. 2013) and NFKB1 footprints are induced in response to infection (Pacis et al. 2015).
