CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Stromal side
CC       {ECO:0000250}. Note=Forms the core of the phycobilisome. {ECO:0000250}.
CC   -!- PTM: Contains one covalently linked bilin chromophore. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the phycobiliprotein family. {ECO:0000305}.
