The central and C-terminal domains of VPg of are important for VPg–HCPro and VPg–VPg interactions Free

Abstract

Interactions between the major proteins of (ClYVV) were investigated using a GAL4 transcription activator-based yeast two-hybrid system (YTHS). Self-interactions manifested by VPg and HCPro and an interaction between NIb and NIaPro were observed in ClYVV. In addition, a strong HCPro–VPg interaction was detected by both YTHS and by far-Western blot analysis in ClYVV. A potyvirus HCPro–VPg interaction has not been reported previously. Using YTHS, domains in ClYVV for the VPg self-interaction and the HCPro–VPg interaction were mapped. The VPg C-terminal region (38 amino acids) was important for the VPg–VPg interaction and the central 19 amino acids were needed for the HCPro–VPg interaction.
