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:0000305}.
CC   -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC       {ECO:0000305}.
