We investigated the interaction of Rice grassy stunt tenuivirus (RGSV) nonstructural protein p5, a protein of 22 kDa encoded on vRNA 5, with all 12 RGSV proteins by using a GAL4 transcription activator-based yeast two-hybrid system. The p5 protein interacted only with itself and not with any other viral protein; the interacting domains were localized within the N-terminal 96 amino acids of p5. The p5-p5 interaction was reproduced in an Sos recruitment-mediated yeast two-hybrid system as well in by far-Western blots. Native p5 protein extracted from RGSV-infected rice tissue was detected in a large complex with a molecular mass of approximately 260 kDa composed of 12 molecules of p5 or a p5 oligomer with an unidentified host factor(s).
