CSNK1D and Salmonella Infections: Using qRT-PCR the expression of some of the KDM6B bound target genes was probed at 4 h p.i. DAAM1, a regulator of cytoskeletal reorganization, PPARδ, a fatty acid oxidation regulator and CSNK1D, a member of casein kinase gene family were found to be up-regulated upon Salmonella infection (Figure 2d).
