CC -!- FUNCTION: Rod linker protein, associated with phycoerythrin. 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: The phycobilisome is a hemidiscoidal structure that is
CC composed of two distinct substructures: a core complex and six rods
CC radiating from the core.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Peripheral membrane
CC protein; Cytoplasmic side. Note=Associated with phycoerythrin.
CC -!- INDUCTION: By green light.
CC -!- SIMILARITY: Belongs to the phycobilisome linker protein family.
CC {ECO:0000255|PROSITE-ProRule:PRU00775}.
