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. {ECO:0000256|ARBA:ARBA00025055,
CC ECO:0000256|PIRNR:PIRNR000083}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000256|PIRNR:PIRNR000083}; Peripheral membrane protein
CC {ECO:0000256|PIRNR:PIRNR000083}; Cytoplasmic side
CC {ECO:0000256|PIRNR:PIRNR000083}. Note=This protein occurs in the rod,
CC it is associated with allophycocyanin. {ECO:0000256|PIRNR:PIRNR000083}.
CC -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC {ECO:0000256|ARBA:ARBA00005304, ECO:0000256|PIRNR:PIRNR000083}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:MBD2034444.1}.
