CC   -!- FUNCTION: One of the components of the core complex of photosystem II
CC       (PSII), required for its stability and/or assembly. PSII is a light-
CC       driven water:plastoquinone oxidoreductase that uses light energy to
CC       abstract electrons from H(2)O, generating O(2) and a proton gradient
CC       subsequently used for ATP formation. It consists of a core antenna
CC       complex that captures photons, and an electron transfer chain that
CC       converts photonic excitation into a charge separation.
CC       {ECO:0000255|HAMAP-Rule:MF_00752}.
CC   -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins PsbA,
CC       PsbB, PsbC, PsbD, numerous small proteins, at least 3 peripheral
CC       proteins of the oxygen-evolving complex and a large number of
CC       cofactors. It forms dimeric complexes. {ECO:0000255|HAMAP-
CC       Rule:MF_00752}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_00752}; Single-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00752}.
CC   -!- PTM: Phosphorylation is a light-dependent reaction catalyzed by a
CC       membrane-bound kinase; phosphorylation occurs on Thr residue(s) in the
CC       N-terminus of the protein. {ECO:0000255|HAMAP-Rule:MF_00752}.
CC   -!- SIMILARITY: Belongs to the PsbH family. {ECO:0000255|HAMAP-
CC       Rule:MF_00752}.
