Protein

Transcriptional regulatory protein CpxR

Gene

cpxR

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Member of the two-component regulatory system CpxA/CpxR. This system combats a variety of extracytoplasmic protein-mediated toxicities. It performs this function by increasing the synthesis of the periplasmic protease, DegP as well as that of CpxP protein.
