Protein attributes

Sequence length	214 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Response regulator in the two-component regulatory system ComP/ComA involved in a major quorum response pathway that regulates the development of genetic competence. Regulates directly the expression of over 20 genes, including genes of the srfA operon, degQ, rapA, rapC, rapE, rapF, etc. Regulates indirectly, through the regulation of comK transcription, the expression of late competence genes. Ref.4
Subcellular location	Cytoplasm Probable.
Post-translational modification	Phosphorylated by ComP.
Sequence similarities	Contains 1 HTH luxR-type DNA-binding domain. Contains 1 response regulatory domain.
