CC -!- FUNCTION: Light-harvesting photosynthetic bile pigment-protein from the
CC phycobiliprotein complex.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta chain.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Peripheral membrane
CC protein; Cytoplasmic side. Note=Forms the periphery of the
CC phycobilisome rod.
CC -!- PTM: Contains two covalently linked phycoerythrobilin chromophores and
CC one covalently linked phycourobilin chromophore.
CC -!- SIMILARITY: Belongs to the phycobiliprotein family. {ECO:0000305}.
