Function
Essential regulator of plant defense, which plays a central role in resistance in case of infection by a pathogen. It is a common target for both type III avirulence proteins from P.syringae (AvrB, AvrRpm1 and AvrRpt2) and for the plant Resistance (R) proteins RPM1 and RPS2. In strains carrying the appropriate R gene for avirulence proteins of the pathogen, its association with avirulence proteins triggers a defense system including the hypersensitive response, which limits the spread of disease. In contrast, in plants lacking appropriate R genes, its association with avirulence proteins of the pathogen impairs the defense system and leads to the pathogen multiplication. UniProt

Subunit Structure
Interacts with the unrelated avirulence proteins AvrB, AvrRpm1 and AvrRpt2 from P.syringae. Interacts with the N-terminal domain of PRM1. Interacts indirectly with RPS2. Its association with AvrB and AvrRpm1 results in its phosphorylation, which is in turn recognized by the resistance RPM1 protein, leading to the activation of RPM1-dependent disease resistance responses. On the other hand, its association with AvrRpt2 results in its destruction, which activates RPS2-dependent disease resistance responses. Interacts (via C-terminus) with NDR1. Interaction with NDR1 is required for association with RPS2 and RPS2-mediated resistance (PubMed:11955429, PubMed:12581526, PubMed:12581527, PubMed:15746386, PubMed:17012600, PubMed:17397263). Interacts with RIPK (PubMed:21320696). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB

Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
