Function

RD54_PHYIT Effector that specifically binds host autophagy protein ATG8CL of the ATG8 family to stimulate autophagosome formation and subsequent autophagy rather than blocking autophagic flux (PubMed:26765567, PubMed:29932422). The pathogen remodels host-microbe interface by co-opting the host autophagy machinery which plays a key role in plant immunity (PubMed:29932422). PexRD54 competes with the autophagy cargo receptor Joka2 to deplete it out of ATG8CL complexes and interferes with Joka2's positive effect on pathogen defense (PubMed:26765567, PubMed:29932422).^[1] ^[2]

Publication Abstract from PubMed

Filamentous plant pathogens deliver effector proteins to host cells to promote infection. The Phytophthora infestans RXLR-type effector PexRD54 binds potato ATG8 via its ATG8-family interacting motif (AIM) and perturbs host selective autophagy. However, the structural basis of this interaction remains unknown. Here we define the crystal structure of PexRD54, which comprises a modular architecture including five tandem repeat domains, with the AIM sequence presented at the disordered C-terminus. To determine the interface between PexRD54 and ATG8, we solved the crystal structure of potato ATG8CL in complex with a peptide comprising the effectors AIM sequence, and established a model of the full-length PexRD54/ATG8CL complex using small angle X-ray scattering. Structure-informed deletion of the PexRD54 tandem domains reveals retention of ATG8CL binding in vitro and in planta. This study offers new insights into structure/function relationships of oomycete RXLR effectors and how these proteins engage with host cell targets to promote disease.
