CC -!- FUNCTION: Chemotactic-signal transducers respond to changes in the
CC concentration of attractants and repellents in the environment,
CC transduce a signal from the outside to the inside of the cell, and
CC facilitate sensory adaptation through the variation of the level of
CC methylation. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the methyl-accepting chemotaxis (MCP) protein
CC family. {ECO:0000305}.
