General annotation (Comments)

Function

Member of a two-component regulatory system QseB/QseC. Activates the flagella regulon by activating transcription of FlhDC. Currently it is not known whether this effect is direct or not. Ref.3

Subcellular location

Cytoplasm Potential.

Induction

By the signal autoinducer AI-2, through MqsR. Ref.4

Post-translational modification

Phosphorylated by QseC Probable.

Sequence similarities

Contains 1 response regulatory domain.
