Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of sporulation specific genes (PubMed:8759874). Interaction with SpoIIAB inhibits sigma-F activity throughout the cell before the formation of the asymmetric septum; after septation the interaction is confined to the mother cell, and sigma F activity is released in the prespore. Responsible for expression of csfB (the anti-sigma-G factor Gin) (PubMed:8759874).

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor (NrsF in this case) until they are released (Probable). Regulates expression of only a few genes (Dsui_0154 to Dsui_0159) in response to (hypo)chlorite, conferring resistance to reactive chlorine species (RCS) during oxic growth (PubMed:25968643).

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor (NrsF in this case) until they are released (Probable). Up-regulates expression of 4 operons (sigF-nrsF, CCNA_02834, CCNA_03001 to CCNA_02999 and CCNA_03363 to CCNA_03366) in response to potassium dichromate (K(2)Cr(2)O(7)) or cadmium chloride (CdCl(2)) (PubMed:22985357).
