CC   -!- FUNCTION: Transduces signals from the phototaxis receptor sensory
CC       rhodopsin II (Sop2). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- INDUCTION: Expressed constitutively throughout the growth phases, both
CC       in presence and absence of white light. {ECO:0000269|PubMed:20802037}.
CC   -!- SIMILARITY: Belongs to the methyl-accepting chemotaxis (MCP) protein
CC       family. {ECO:0000305}.
