CC   -!- FUNCTION: Rod linker protein, associated with phycoerythrocyanin.
CC       Linker polypeptides determine the state of aggregation and the location
CC       of the 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   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Peripheral membrane
CC       protein; Cytoplasmic side. Note=This protein occurs in the rod, it is
CC       associated with phycoerythrocyanin.
CC   -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00775}.
