Abstract: To identify host proteins interacting with the membrane-bound replication proteins of tombusviruses, we performed membrane yeast two-hybrid (MYTH) screens based on yeast cDNA libraries. The screens led to the identification of 57 yeast proteins interacting with replication proteins of two tombusviruses. Results from a split ubiquitin assay with 12 full-length yeast proteins and the viral replication proteins suggested that the replication proteins of two tombusviruses interact with a similar set of host proteins. Follow-up experiments with the yeast Cpr1p cyclophilin, which has prolyl isomerase activity that catalyzes cis-trans isomerization of peptidyl-prolyl bonds, confirmed that Cpr1p interacted with the viral p33 replication protein in yeast and in vitro. Replication of Tomato bushy stunt virus replicon RNA increased in cpr1Delta yeast, while over-expression of Cpr1p decreased viral replication. We also show that the Ess1p parvulin prolyl isomerase partly complements Cpr1p function as an inhibitor of tombusvirus replication.CI - Copyright (c) 2010. Published by Elsevier Inc.
