RA Liu J., Wan J., Wang D., Wen C., Wei Y., Ouyang Z.; RL Submitted (SEP-2020) to the EMBL/GenBank/DDBJ databases. 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 -!- 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:0000256|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:0000256|ARBA:ARBA00038734, ECO:0000256|HAMAP- CC Rule:MF_00644}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Plastid, CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_00644}; CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00644}. CC -!- SIMILARITY: Belongs to the PsbZ family. {ECO:0000256|ARBA:ARBA00008367, CC ECO:0000256|HAMAP-Rule:MF_00644, ECO:0000256|RuleBase:RU003472}.
