CC -!- FUNCTION: Involved in nitrate transport, but does not seem to be able
CC to mediate transport by its own. Acts as a dual component transporter
CC with NAR2.1. Imports nitrate with high affinity when expressed with
CC NAR2.1 in a heterologous system (Xenopus oocytes).
CC {ECO:0000269|PubMed:21220781, ECO:0000269|PubMed:21486304,
CC ECO:0000269|Ref.1}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=34 uM for nitrate {ECO:0000269|PubMed:21486304};
CC -!- SUBUNIT: Heterotetramer composed of two NRT2.1 and two NAR2.1 (By
CC similarity). Interacts with NAR2.1. {ECO:0000250,
CC ECO:0000269|PubMed:21486304}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in primary and lateral roots, root-shoot
CC junction zone, vascular tissues of adventitious root primordia, leaves
CC and at the base of the embryo in germinating seeds.
CC {ECO:0000269|PubMed:21220781}.
CC -!- INDUCTION: Circadian-regulation with a peak in the middle of the
CC morning. Induced by nitrate and sucrose in roots. Down-regulated by
CC ammonium, glutamine, asparagine and aspartate in roots.
CC {ECO:0000269|PubMed:20862512, ECO:0000269|PubMed:21220781,
CC ECO:0000269|PubMed:21486304}.
CC -!- MISCELLANEOUS: Plants over-expressing NRT2.1 have accelerated growth
CC under low nitrate conditions (Ref.1).
CC -!- SIMILARITY: Belongs to the major facilitator superfamily.
CC Nitrate/nitrite porter (TC 2.A.1.8) family. {ECO:0000305}.
