UniprotKB/SwissProt ID: Q8W453 (Q8W453)
Gene Name:
DIR1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Putative lipid transfer protein required for systemic acquired resistance (SAR) long distance signaling. May interact with a lipid-derived molecule to promote long distance signaling associated with SAR. Together with AZI1, required for glycerol-3-phosphate- (G3P) and azelaic acid- (AA) induced systemic acquired resistance (SAR). Component of plant systemic immunity involved in priming defenses in a AA-dependent manner, by modulating production and/or translocation of a mobile signal(s) during SAR. Is able to bind with high affinity monoacylated phospholipids, mainly lysophosphatidylcholines (PubMed:18552128)
