CC phycobiliprotein in the PBS rod. {ECO:0000256|ARBA:ARBA00003579}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000256|ARBA:ARBA00004445, ECO:0000256|RuleBase:RU004438};
CC Peripheral membrane protein {ECO:0000256|ARBA:ARBA00004445,
CC ECO:0000256|RuleBase:RU004438}; Cytoplasmic side
CC {ECO:0000256|ARBA:ARBA00004445, ECO:0000256|RuleBase:RU004438}.
CC Membrane {ECO:0000256|ARBA:ARBA00004287}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004287}; Cytoplasmic side
CC {ECO:0000256|ARBA:ARBA00004287}.
CC -!- SIMILARITY: Belongs to the phycobiliprotein family.
