CC   -!- FUNCTION: One of the components of the core complex of photosystem II
CC       (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that
CC       uses light energy to abstract electrons from H(2)O, generating O(2) and
CC       a proton gradient subsequently used for ATP formation. It consists of a
CC       core antenna complex that captures photons, and an electron transfer
CC       chain that converts photonic excitation into a charge separation. This
CC       subunit is found at the monomer-monomer interface and is required for
CC       correct PSII assembly and/or dimerization. {ECO:0000255|HAMAP-
CC       Rule:MF_01317}.
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       PsbX, PsbY, PsbZ, 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_01317}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01317}; Single-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01317}.
CC   -!- SIMILARITY: Belongs to the PsbL family. {ECO:0000255|HAMAP-
CC       Rule:MF_01317}.
