ATPT2 — Arabidopsis thaliana

Summary

AT2G38940 (AtPT2, also known as PHT1;4) encodes a phosphate transporter belonging to the major facilitator superfamily (MFS). The protein possesses phosphate transmembrane transporter, arsenate ion transmembrane transporter, and symporter activities, and is localised to the plasma membrane, vacuole, Golgi complex, plasmodesmata, and cytoplasm. AtPT2 is associated with phosphate ion transport, regulation of phosphate transport, arsenate ion transmembrane transport, nitrate import, acid secretion, pH reduction, and lateral root development. The gene has been connected to phosphorus concentration and uptake, root hair density and branching, root length, leaf chlorosis, anthocyanin content, drought tolerance, temperature stress tolerance, and responses to lead and chromium. Associations with arsenic accumulation, selenium uptake, antimony tolerance, and bacterial immunity have also been reported. Related genes in other species are linked to phosphate transport.
