CC   -!- FUNCTION: Associated with the reaction center - light-harvesting
CC       complex I. May play a critical role in facilitating the interaction
CC       between this complex and other components required for light-driven
CC       cyclic electron transfer.
CC   -!- SUBCELLULAR LOCATION: Cell membrane.
CC   -!- SIMILARITY: Belongs to the PufX family. {ECO:0000305}.
