CC   -!- FUNCTION: Controls the interaction of photosystem II (PSII) cores with
CC       the light-harvesting antenna, regulates electron flow through the 2
CC       photosystem reaction centers. PSII is a light-driven water
CC       plastoquinone oxidoreductase, using light energy to abstract electrons
CC       from H(2)O, generating a proton gradient subsequently used for ATP
CC       formation. {ECO:0000256|RuleBase:RU003472}.
CC   -!- SIMILARITY: Belongs to the PsbZ family. {ECO:0000256|ARBA:ARBA00008367,
CC       ECO:0000256|RuleBase:RU003472}.
