CC   -!- FUNCTION: May play a role in photosystem I and II biogenesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00293}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_00293}; Single-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00293}.
CC   -!- SIMILARITY: Belongs to the PsbN family. {ECO:0000255|HAMAP-
CC       Rule:MF_00293}.
CC   -!- CAUTION: Originally thought to be a component of PSII; based on
CC       experiments in Synechocystis, N.tabacum and barley, and its absence
CC       from PSII in T.elongatus and T.vulcanus, this is probably not true.
