CpxR coding region

CpxR is a transciption factor that dimerizes and becomes active when phosphorylated by the transmembrane histidine kinase CpxA. CpxA becomes active when the bacterial cell is submitted to different kinds of shock (pH, temperature, pressure, protein misfolding in the inter-membrane space...).

It is a response regulator of the regulatory system 'CpxA/CpxR', which is a 2 component regulatory system. It responds to the envelope stress response with the activation of the downstream genes including cpxP, degP, dsbA and ppiA. [1] Cite error: Closing </ref> missing for <ref> tag

This system combats a variety of extracytoplasmic protein-mediated toxicities by increasing the transcription of the periplasmic protease, DegP in concert with sigma factor E, as well as that of CpxP protein. Other downstream effectors may include SrkA.
