The multifunctional protein helper component proteinase (HC-Pro) is thought to interfere with the activity of the 20S proteasome; however, no sites of interaction have been identified for either protein. Here, we first show that the Potato virus Y (PVY) HC-Pro protein can interact with three Arabidopsis 20S proteasome subunits (PAA, PBB, and PBE), using a yeast two-hybrid system and the bimolecular fluorescence complement assay. In addition, yeast two-hybrid analysis of the interaction between… CONTINUE READING
