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}.
