CC -!- FUNCTION: Rod linker protein, associated with allophycocyanin. Linker
CC polypeptides determine the state of aggregation and the location of the
CC disk-shaped phycobiliprotein units within the phycobilisome and
CC modulate their spectroscopic properties in order to mediate a directed
CC and optimal energy transfer (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC {ECO:0000250}. Note=This protein occurs in the rod, it is associated
CC with allophycocyanin. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC {ECO:0000305}.
