Protein: Disease resistance protein RPS2 (Resistance to Pseudomonas syringae protein 2) (Q42484)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Disease resistance (R) protein that specifically recognizes the AvrRpt2 type III effector avirulence protein from Pseudomonas 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. Acts via its interaction with RIN4, and probably triggers the plant resistance when RIN4 is degraded by AvrRpt2.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:8986840}. Cell membrane {ECO:0000269|PubMed:12581526}. Note=Not a peripheral membrane protein. Has the biochemical properties of an integral membrane protein without an obvious integral membrane primary structure. {ECO:0000269|PubMed:12581526}.
