CC -!- FUNCTION: Voltage-dependent rectifying anion channel that facilitates
CC the translocation between chloroplast and cytoplasm of phosphorylated
CC carbohydrates such as triosephosphate, 3-phosphoglycerate and inorganic
CC phosphate (Pi) depending of ATP to triosephosphate ratio in the
CC plastidial intermembrane space; in high triosephosphate/ATP conditions
CC (e.g. photosynthesis), export of triosphosphate from chloroplast
CC (outward rectifying channels), but in high ATP/triosephosphate
CC conditions (e.g. dark phase), import of phosphosolutes (inward
CC rectifying channels) (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid, etioplast membrane {ECO:0000250}; Multi-
CC pass membrane protein {ECO:0000250}. Plastid, chloroplast outer
CC membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
CC Note=Present in non-green root plastids. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the plastid outer envelope porin OEP21 (TC
CC 1.B.29) family. {ECO:0000305}.
