Also acts as a suppressor of RNA-mediated gene silencing, also known as post-transcriptional gene silencing (PTGS), a mechanism of plant viral defense that limits the accumulation of viral RNAs. Publication Abstract from PubMed The structure of turnip crinkle virus has been determined at 3.2 A resolution, using the electron density of tomato bushy stunt virus as a starting point for phase refinement by non-crystallographic symmetry. The structures are very closely related, especially in the subunit arm and S domain, where only small insertions and deletions and small co-ordinate shifts relate one chain to another. The P domains, although quite similar in fold, are oriented somewhat differently with respect to the S domains. Understanding of the structure of turnip crinkle virus has been important for analyzing its assembly, as described in an accompanying paper. Structure and assembly of turnip crinkle virus. I.
