CC -!- FUNCTION: Receptor for the attractant L-serine and related amino acids.
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. Attractants increase the level of methylation while
CC repellents decrease the level of methylation, the methyl groups are
CC added by the methyltransferase CheR and removed by the methylesterase
CC CheB.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC -!- SIMILARITY: Belongs to the methyl-accepting chemotaxis (MCP) protein
CC family. {ECO:0000305}.
