CC -!- FUNCTION: May control the interaction of photosystem II (PSII) cores
CC with the light-harvesting antenna, regulates electron flow through the
CC 2 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:0000255|HAMAP-Rule:MF_00644}.
CC -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins PsbA,
CC PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT,
CC PsbY, PsbZ, Psb30/Ycf12, at least 3 peripheral proteins of the oxygen-
CC evolving complex and a large number of cofactors. It forms dimeric
CC complexes. {ECO:0000255|HAMAP-Rule:MF_00644}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_00644}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_00644}.
CC -!- SIMILARITY: Belongs to the PsbZ family. {ECO:0000255|HAMAP-
CC Rule:MF_00644}.
