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   -!- 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:1743523,
CC       ECO:0000269|PubMed:24550276}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000269|PubMed:24550276}; Peripheral membrane protein; Cytoplasmic
CC       side. Note=Part of a phycobilisome rod associated with
CC       phycoerythrocyanin. {ECO:0000269|PubMed:24550276}.
CC   -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00775}.
