CC -!- FUNCTION: A core subunit of photosystem II (PSII). PSII is a light-
CC driven water plastoquinone oxidoreductase, using light energy to
CC abstract electrons from H(2)O, generating a proton gradient
CC subsequently used for ATP formation. {ECO:0000269|PubMed:19433803,
CC ECO:0000269|PubMed:23426624}.
CC -!- COFACTOR:
CC Note=PSII binds multiple chlorophylls, carotenoids and specific lipids.
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260,
CC ECO:0000269|PubMed:23426624};
CC -!- SUBUNIT: Cyanobacterial PSII is composed of 1 copy each of membrane
CC proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK,
CC PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, 3 peripheral proteins PsbO,
CC PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.

CC ECO:0000269|PubMed:23426624}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260,
CC ECO:0000269|PubMed:23426624}; Single-pass membrane protein

CC ECO:0000269|PubMed:23426624}.
CC -!- SIMILARITY: Belongs to the Ycf12 family. {ECO:0000305}.
