CC -!- FUNCTION: Low-affinity transporter for external inorganic phosphate
CC (Pi) probably involved in the acquisition of phosphate released by
CC arbuscular mycorrhizal (AM) fungi during AM symbiosis.
CC {ECO:0000305|PubMed:18315538}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NH4(+)(in) = NH4(+)(out); Xref=Rhea:RHEA:28747,
CC ChEBI:CHEBI:28938; Evidence={ECO:0000250|UniProtKB:Q8GSG4};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q8GSG4};
CC Multi-pass membrane protein {ECO:0000255}. Note=Present on the
CC periarbuscular membrane in cells containing arbuscules during
CC arbuscular mycorrhizal (AM) symbiosis with AM fungi.
CC {ECO:0000250|UniProtKB:Q8GSG4}.
CC -!- TISSUE SPECIFICITY: Expressed at low levels in non-mycorrhized roots.
CC {ECO:0000269|PubMed:18315538}.
CC -!- INDUCTION: Accumulates during arbuscular mycorrhiza (AM) formation
CC after inoculation with AM fungi (e.g. Glomus intraradices).
CC {ECO:0000269|PubMed:18315538}.
CC -!- MISCELLANEOUS: Although related to the sugar transporter family, it
CC does not transport sugars. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily.
CC phosphate:H(+) symporter (TC 2.A.1.9) family. {ECO:0000305}.
