RNA polymerase-binding protein DksA; The model that is the basis for this family describes a small, pleiotropic protein, DksA (DnaK suppressor A), originally named as a multicopy suppressor of temperature sensitivity of dnaKJ mutants. DksA mutants are defective in quorum sensing, virulence, etc. DksA is now understood to bind RNA polymerase directly and modulate its response to small molecules to control the level of transcription of rRNA. Nearly all members of this family are in the Proteobacteria. Whether the closest homologs outside the Proteobacteria function equivalently is unknown. The low value set for the noise cutoff allows identification of possible DksA proteins from outside the proteobacteria. TIGR02419 describes a closely related family of short sequences usually found in prophage regions of proteobacterial genomes or in known phage.
