RA   Apte S.K., Uhlemann E., Schmid R., Altendorf K.;
RL   Submitted (OCT-2001) to UniProtKB.
CC   -!- FUNCTION: Light-harvesting photosynthetic bile pigment-protein from the
CC       phycobiliprotein complex (phycobilisome, PBS). Phycocyanin is the major
CC       phycobiliprotein in the PBS rod. {ECO:0000305}.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta subunit, which further
CC       assembles into trimers and the trimers into hexamers.
CC       {ECO:0000250|UniProtKB:P06539}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000250|UniProtKB:P84341}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:P84341}; Cytoplasmic side
CC       {ECO:0000250|UniProtKB:P84341}. Note=Part of the phycobilisome rod.
CC       {ECO:0000250|UniProtKB:P84341}.
CC   -!- PTM: Contains two covalently linked bilin chromophores.
CC       {ECO:0000250|UniProtKB:P06539}.
CC   -!- SIMILARITY: Belongs to the phycobiliprotein family. {ECO:0000255}.
