Type: | Family | Name: | High-affinity nitrate transporter |
Description: | This group represents a high affinity nitrate transporter component from plants. It includes high-affinity nitrate transporter 3.1 (NRT3.1 or NAR2.1) from Arabidopsis, which acts as a dual component transporter with NTR2 [, ]. The functional unit for high-affinity nitrate influx may be a tetramer consisting of two subunits each of NRT2.1 and NRT3.1 []. NRT3.1 may be involved in targeting NRT2 proteins to the plasma membrane []. Both NRT2.1 and NRT3.1 are coordinately down-regulated by high external nitrate []. | Short Name: | Transptr_NO3_Nar2 |
