General annotation (Comments)

Function

Rod linker protein, associated with allophycocyanin. Linker polypeptides determine the state of aggregation and the location of the disk-shaped phycobiliprotein units within the phycobilisome and modulate their spectroscopic properties in order to mediate a directed and optimal energy transfer By similarity.

Subcellular location

Cellular thylakoid membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: This protein occurs in the rod, it is associated with allophycocyanin By similarity.

Sequence similarities

Belongs to the phycobilisome linker protein family.

Contains 1 cpcD-like domain.
