CC -!- FUNCTION: Rod-core linker protein required for attachment of CC phycocyanin to allophycocyanin in cores of phycobilisomes. CC -!- FUNCTION: Linker polypeptides determine the state of aggregation CC and the location of the disk-shaped phycobiliprotein units within CC the phycobilisome and modulate their spectroscopic properties in CC order to mediate a directed and optimal energy transfer. CC -!- SUBUNIT: The phycobilisome is a hemidiscoidal structure that is CC composed of two distinct substructures: a core complex and a CC number of rods radiating from the core. CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Peripheral CC membrane protein; Cytoplasmic side (By similarity). CC -!- SIMILARITY: Belongs to the phycobilisome linker protein family. CC -!- SIMILARITY: Contains 1 PBS-linker domain.
