{{DISPLAYTITLE:rpoF}}

The gene rpoF (RNA polymerase, flagellum F) encodes the sigma factor sigma-28 (σ28, or RpoF), a protein in Escherichia coli and other species of bacteria. Depending on the bacterial species, this gene may be referred to as sigD{{cite journal|last1=Helmann|first1=JD|last2=Márquez|first2=LM|last3=Chamberlin|first3=MJ|title=Cloning, sequencing, and disruption of the Bacillus subtilis sigma 28 gene.|journal=Journal of Bacteriology|date=Apr 1988|volume=170|issue=4|pages=1568–74|doi=10.1128/jb.170.4.1568-1574.1988 |pmid=2832368|pmc=211003}} or fliA.{{cite journal|last1=Fitzgerald|first1=DM|last2=Bonocora|first2=RP|last3=Wade|first3=JT|title=Comprehensive Mapping of the Escherichia coli Flagellar Regulatory Network.|journal=PLOS Genetics|date=Oct 2014|volume=10|issue=10|pages=e1004649|pmid=25275371|doi=10.1371/journal.pgen.1004649|pmc=4183435 |doi-access=free }} The protein encoded by this gene has been found to be necessary for flagellum formation.{{cite journal|last1=Makinoshima|first1=H.|last2=Aizawa|first2=S.-I.|last3=Hayashi|first3=H.|last4=Miki|first4=T.|last5=Nishimura|first5=A.|last6=Ishihama|first6=A.|title=Growth Phase-Coupled Alterations in Cell Structure and Function of Escherichia coli|journal=Journal of Bacteriology|date=15 February 2003|volume=185|issue=4|pages=1338–1345|doi=10.1128/JB.185.4.1338-1345.2003|pmc=142870|pmid=12562804}}{{cite journal|last1=Starnbach|first1=M.
