Function
Disease resistance (R) protein that specifically recognizes the AvrRps4 type III effector avirulence protein from P.syringae. Resistance proteins guard the plant against pathogens that contain an appropriate avirulence protein via an indirect interaction with this avirulence protein. That triggers a defense system including the hypersensitive response, which restricts the pathogen growth. The combined presence of both regular and alternative RPS4 transcripts with truncated open reading frames (ORFs) is necessary for function (PubMed:17951452). RPS4 function is regulated at multiple levels, including gene expression, alternative splicing, and protein stability (PubMed:17951452). When over-expressed, confers temperature-conditioned EDS1-dependent auto-immunity (PubMed:24146667). Heterodimerization with RRS1 is required to form a functional complex to recognize AvrRps4 and PopP2 (PubMed:24744375). Abscisic acid deficiency enhances nuclear accumulation of RPS4 and its cell death-inducing activity (PubMed:22454454). UniProt

Subunit Structure
Interacts with EDS1 (PubMed:22158818, PubMed:22158819). Interacts with SRFR1 (PubMed:21079790). Interacts with RRS1 (PubMed:24744375). UniProt
Domain
The TIR domain is a signaling domain involved in cell death induction (PubMed:19132868). It is involved in homo- and heterodimerization, but other domains also contribute to the interaction (PubMed:24744375). The LRR domain may interact directly with pathogen-derived elicitors (PubMed:10571887). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
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.
