The '''bacteriophage repressor''' controls the genetic switch determining the lytic cycle following phage infection. It competes with the '''Cro protein''' which selects for the lysogenic cycle. <scene name='55/554906/Cv/2'>Phage 434 repressor cI protein with DNA operator site OR3</scene> ([[1per]]). <ref>PMID:8081737</ref> For details see [[Lambda repressor]].
