fis is an activator of ribosomal RNA transcription as well as other genes, as a key part in upstream up-regulation of rRNA promoters [1].

It binds to a recombinatorial enhancer helix-turn-helix sequence motif, facilitating hin-mediated DNA inversion [2] as well as binding to hundreds of transcriptionally active and inactive AT-rich sites [3] approximately half of which are located in non-coding DNA [4].

It prevents the initiation of oriC-mediated DNA replication [5].
