IKKβ phosphorylation regulates RPS3 nuclear translocation and NF-κB function during infection with Escherichia coli strain O157:H7.

Abstract excerpt

NF-κB is a major gene regulator in immune responses, and ribosomal protein S3 (RPS3) is an NF-κB subunit that directs specific gene transcription. However, it is unknown how nuclear translocation of RPS3 is regulated. Here we report that phosphorylation of RPS3 Ser209 by the kinase IKKβ was crucial for nuclear localization of RPS3 in response to activating stimuli. Moreover, virulence protein NleH1 of the...
