Plasmodesmata-located protein 5

UniProtKB accession:  Q8GUJ2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Modulates cell-to-cell trafficking. Has a positive role in innate immunity. Required for systemic acquired resistance (SAR) which is mediated by the signaling molecules azelaic acid (AzA), glycerol-3-phosphate (G3P), and salicylic acid (SA) (PubMed:27078071). Negative regulator of plasmodesmata permeability triggered by SA during immune responses, through regulation of callose deposition (PubMed:21934146, PubMed:23749844). Delays the trafficking of Tobacco Mosaic Virus (TMV) movement protein (MP). Required for symplastic signal transport (PubMed:27078071).
