Accession ID Name Pfam Type
PF07022 Bacteriophage CI repressor helix-turn-helix domain domain

This family consists of several phage CI repressor proteins and related bacterial sequences. The CI repressor is known to function as a transcriptional switch, determining whether transcription is lytic or lysogenic [1].
