Gene : PTR1 A. thaliana

DB identifier  ? AT3G54140 Secondary Identifier  ? locus:2080235
Name  ? peptide transporter 1 Brief Description  peptide transporter 1
TAIR Computational Description  peptide transporter 1;(source:Araport11)
TAIR Curator Summary  Encodes a di- and tri-peptide transporter that recognizes a variety of different amino acid combinations. GFP-tagged PTR1 localizes to the plasma membrane and has 8 to 11 predicted transmembrane domains. PTR1 is expressed in a number of different vascular tissues throughout the plant based on promoter:GUS expression analysis. ptr1 mutants have a lower dry weight than wild type plants when both are grown with Pro-Ala or Ala-Ala dipeptides as their nitrogen source, suggesting that PTR1 plays a role in dipeptide uptake in the roots. Furthermore N content of ptr1 mutants is lower than that of wild type plants when grown with Pro-Ala or a mixture of dipeptides as nitrogen source
