Arabidopsis-P. syringae system<br />
B. RPS2 is an NB-LRR protein that resides at the plasma<br />
membrane. It is activated by the AvrRpt2 cysteine<br />
protease type <strong>II</strong>I effector from P. syringae. Autoprocessing<br />
of AvrRpt2 by a host cyclophilin reveals a<br />
consensus, but unconfirmed, myristoylation site at the<br />
new amino terminus, suggesting that it might also be<br />
localized to the host plasma membrane. AvrRpt2 is the<br />
third effector that targets RIN4. Cleavage of RIN4 by<br />
AvrRpt2 leads to RPS2-mediated ETI. In the absence<br />
of RPS2, AvrRpt2 presumably cleaves RIN4 and other<br />
targets as part of its virulence function.
