摘要: The yeast two-hybrid (Y2H) assay, a powerful tool for identifying protein-protein interactions, has been widely used to study viral protein interactions and to elucidate the functions of viral proteins. In this study, Cucurbit chlorotic yellows virus-encoded proteins were investigated by Y2H assays in all possible pairwise combinations, and the self-interactions of P59 and P9 were detected. The interacting domains of P59 and P9 were identified using vectors carrying an activation domain fused to a truncated version of P59 or P9. We found that the middle region (amino acids 173-344) of P59 was necessary for this self-interaction, while three different truncated versions of P9 showed no interaction with full-length P9. This is the first report of the self-interaction of P59 in the genus Crinivirus,
