A sigma factor (σ factor or specificity factor) is a protein needed for initiation of transcription in bacteria. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters.

WebSigma factors are further subdivided into the sigma70 and sigma54 classes, though there is no sequence homology between the two. Members of the sigma70 class of sigma factors are immediately active upon binding to the DNA and the core RNA polymerase, so transcription initiation occurs as soon as sigma70 proteins are translated.
