Fig. 5From: The Function of Rac Small GTPase and Associated Proteins in Rice Innate ImmunityThe Hop/Sti1-HSP90 chaperone complex facilitates the maturation and transport of PRRs. The rice chitin receptor OsCERK1 interacts with HSP90 and its chaperone Hop/Sti1 in the ER. Hop/Sti1 and HSP90 are required for efficient transport of OsCERK1 from the ER to the plasma membrane via ER-to-Golgi trafficking. Further, Hop/Sti1 and HSP90 interact with OsRac1 and OsCERK1. The Hop/Sti1-HSP90 chaperone complex plays an important and conserved role in the maturation and transport of PRRs.Back to article page
