Family

High-affinity nitrate transporter (IPR016605)

Short name: Transptr_NO3_Nar2

Family relationships

None.

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 [PMID: 16415212, PMID: 17012411]. The functional unit for high-affinity nitrate influx may be a tetramer consisting of two subunits each of NRT2.1 and NRT3.1 [PMID: 20561257]. NRT3.1 may be involved in targeting NRT2 proteins to the plasma membrane [PMID: 19704673]. Both NRT2.1 and NRT3.1 are coordinately down-regulated by high external nitrate [PMID: 16998085].
