Název v původním jazyce

C-terminal hydrophobic region leads PRSV P3 Protein to endoplasmic reticulum

Popis výsledku v původním jazyce

P3 protein is one of the least characterized potyviral proteins in both functions and sub-cellular localization. In this study, we examined the sub-cellular localization of PRSV P3 and its intermediate, P3-6K1 by expressing their GFP fusion proteins in onion epidermal cells. Our results showed that both P3- and P3-6K1 GFP fusion proteins were localized at the endoplasmic reticulum. Deletion analysis indicated that C-terminal of P3 protein contained localization signal, and a 19 amino acids hydrophobic domain from this region was able to target the GFP fusion protein to endoplasmic reticulum. C-terminal of P3 proteins has been suggested to be involved in both viability and pathogenicity of the potyvirus. Therefore, our result suggests that localizationof P3 protein at endoplasmic reticulum is essential for functionality of P3 protein.
