CC   -!- FUNCTION: Stabilizes dimeric photosystem II (PSII). In its absence no
CC       dimeric PSII accumulates and there is a reduction of monomeric PSII (By
CC       similarity). {ECO:0000250|UniProtKB:Q39194}.
CC   -!- SUBUNIT: Part of the photosystem II complex. PSII is composed of 1 copy
CC       each of membrane proteins PsbA, PsbB, PsbC, PsbD, numerous small
CC       proteins, at least 3 peripheral proteins of the oxygen-evolving complex
CC       and a large number of cofactors. It forms dimeric complexes.
CC       {ECO:0000250|UniProtKB:Q41387}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000250|UniProtKB:Q41387}; Single-pass membrane protein. Note=The
CC       N-terminus is found within the thylakoid lumen (By similarity).
CC       {ECO:0000250|UniProtKB:Q41387}.
CC   -!- SIMILARITY: Belongs to the psbW family. {ECO:0000305}.
