Regulation summary diagram for uspC

UspC, UspD, and UspE play nonredundant and probably sequential roles in a pathway involved in resistance to UV irradiation [Gustavsson02].

Mutation of the uspC, uspD, or uspE gene causes decreased resistance to UV irradiation [Gustavsson02].

Under conditions of salt stress UspC is believed to act as a scaffolding protein for the KdpD/KdpE phosphorylation cascade. UspC interacts with the usp domain of KdpD sensory histidine kinase / protein phosphatase and stable complexes of UspC/KdpD/phosphorylated KdpE/DNA have been observed in vitro. uspC null mutants show down regulation of KdpFABC production under conditions of salt stress [Heermann09, Heermann09a].

The protein has been detected and mapped on a 2-D gel [Gustavsson02].

Regulation has been described [Gustavsson02]. The uspC, uspD, and uspE genes appear to be coregulated; the stresses that act as inducers and the genetics of this regulation is examined [Gustavsson02].

UspC: "universal stress protein" [Gustavsson02].
