Natl. Acad. Sci. U.S.A. 111:2512-2517(2014). CC -!- FUNCTION: Rod-core linker protein required for attachment of CC phycocyanin to allophycocyanin in cores of phycobilisomes. CC -!- FUNCTION: Linker polypeptides determine the state of aggregation and CC the location of the disk-shaped phycobiliprotein units within the CC phycobilisome and modulate their spectroscopic properties in order to CC mediate a directed and optimal energy transfer. CC -!- SUBUNIT: Part of the phycobilisome, a hemidiscoidal structure that is CC composed of two distinct substructures: a core complex and a number of CC 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 CC {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Part of a CC phycobilisome rod. {ECO:0000269|PubMed:24550276}. CC -!- SIMILARITY: Belongs to the phycobilisome linker protein family. CC {ECO:0000255|PROSITE-ProRule:PRU00775}.
