CC -!- FUNCTION: May be involved in the regulation of photosystem II.
CC {ECO:0000250|UniProtKB:P12302}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000250|UniProtKB:P12302}. Note=Associated with the photosystem II
CC complex. {ECO:0000250|UniProtKB:P12302}.
CC -!- INDUCTION: Down-regulated in response to mixed metal ion contamination
CC (cadmium, copper, lead and zinc), but not in response to zinc ion
CC contamination. {ECO:0000269|Ref.2}.
CC -!- SIMILARITY: Belongs to the psbP family. {ECO:0000255}.
