In molecular biology, the flagellar motor switch protein (Flig) is one of three proteins in certain bacteria coded for by the gene fliG. The other two proteins are FliN coded for by fliN, and FliM coded for by fliM. The protein complex regulates the direction of flagellar rotation and hence controls swimming behaviour. The switch is a complex apparatus that responds to signals transduced by the chemotaxis sensory signalling system during chemotactic behaviour.
