CC   -!- FUNCTION: Rod-core linker protein required for attachment of
CC       phycocyanin to allophycocyanin in cores of phycobilisomes.
CC       {ECO:0000250}.
CC   -!- FUNCTION: Linker polypeptides determine the state of aggregation and
CC       the location of the disk-shaped phycobiliprotein units within the
CC       phycobilisome and modulate their spectroscopic properties in order to
CC       mediate a directed and optimal energy transfer. {ECO:0000250}.
CC   -!- SUBUNIT: The phycobilisome is a hemidiscoidal structure that is
CC       composed of two distinct substructures: a core complex and a number of
CC       rods radiating from the core. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00775}.
