High affinity abscisic acid (ABA) transporter that mediates the export of ABA, with a preference for (+)-ABA, through the plasma membrane, especially in vascular tissues (e.g. phloem companion cells), and is involved in the intercellular ABA signaling pathway (PubMed:20133881, PubMed:20935463, PubMed:24521878, PubMed:26517905). Together with ABCG31, export ABA from the endosperm to deliver it to the embryo via ABCG30 and ABCG40-mediated import to suppress radicle extension and subsequent embryonic growth (PubMed:26334616). abscisate(in) + ATP + H2O = abscisate(out) + ADP + H(+) + phosphate ADP and vanadate (ABC transporters inhibitor) inhibit the ATP-dependent abscisic acid (ABA) uptake. Mainly expressed in vascular tissues,predominantly in phloem companion cells, with highest levels in roots and seeds, and lower levels in seedlings, stems, leaves and flowers (PubMed:20133881, PubMed:24521878). Mostly observed in inflorescence meristems relative to cauline leaves and developing siliques (PubMed:22525244). In seeds, mainly expressed in the endosperm and, to a lesser extent, in the embryo (PubMed:26334616). By abscisic acid (ABA) (PubMed:20133881). In cauline leaves, activated by cold stress, but repressed by heat stress (PubMed:22525244). Within inflorescence meristems, down-regulated by both cold and heat stress treatments (PubMed:22525244). In developing siliques, activated by cold stress, but unaffected by heat stress (PubMed:22525244). Hypersensitivity to abscisic acid (ABA). Belongs to the ABC transporter superfamily. ABCG family. Eye pigment precursor importer (TC 3.A.1.204) subfamily.
