Protein
Protein GLUTAMINE DUMPER 1
Organism
Arabidopsis thaliana
Function
Probable subunit of an amino acid transporter involved in the regulation of the amino acid metabolism. Stimulates amino acid export by activating nonselective amino acid facilitators. Required the interaction with the RING-type E3 ubiquitin-protein ligase LOG2 to fulfill its function. Plays a role in the Gln export at hydathodes, at xylem parenchyma into xylem sap and from mesophyll into leaf apoplasm. Acts upstream genes involved in the salicylic acid (SA) pathway and in the geminivirus-host interaction.
Similarity
Belongs to the GLUTAMINE DUMPER 1 (TC 9.B.60) family.
