Abstract excerpt
We previously presented that calmodulin-dependent kinase IV (CaMKIV) mutually interacts with NF-kappa B and phosphorylates it directly, inducing the increased transcriptional regulation dependent on NF-kappa B target genes [J. Biol. Chem. 276 (2001) 20005]. Here, we show that Ser(535) residue is phosphorylated by CaMKIV. S535A mutant of p65 was specifically defective in transactivation of NF-kappa B target gene...
