Function
Controls the expression of the cellular protein quality control genes clpC, clpE and clpP, as well as mcsA and mcsB, by acting as a repressor of these class III stress genes. After heat shock, CtsR is degraded by the ClpCP and ClpEP proteolytic systems, ensuring the derepression of clpE, clpP and the clpC operon. CtsR negatively autoregulates its own synthesis (By similarity).
