CC   -!- FUNCTION: Rod linker protein, associated with phycocyanin. 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.
CC   -!- SUBUNIT: Associated with the phycobilisome, a hemidiscoidal structure
CC       that is composed of two distinct substructures: a core complex and a
CC       number of rods radiating from the core. {ECO:0000269|PubMed:24550276}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000269|PubMed:24550276}; Peripheral membrane protein
CC       {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=This protein occurs
CC       in the rod, it is associated with phycocyanin.
CC       {ECO:0000269|PubMed:24550276, ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC       {ECO:0000305}.
