Virology Journal 2011, eight:298 http:www.virologyj.comcontent81RESEARCHOpen AccessThe distinct binding properties between avian human Nikkomycin Z MedChemExpress influenza A virus NS1 and Postsynaptic density protein-95 (PSD-95), and inhibition of nitric oxide productionHeng Zhang, Weizhong Li, Gefei Wang, Yun Su, Chi Zhang, Xiaoxuan Chen, Yanxuan Xu and Kangsheng LiAbstractBackground: The NS1 protein of influenza A virus is able to bind with numerous proteins that impact cellular signal transduction and protein synthesis in infected cells. The NS1 protein consists of roughly 230 amino acids plus the last four amino acids of your NS1 C-terminal form a PDZ binding motif. Postsynaptic Density Protein-95 (PSD-95), which is mainly expressed in neurons, has three PDZ domains. We hypothesise that NS1 binds to PSD-95, and this binding is capable to influence neuronal function. Outcome: We carried out a yeast two-hybrid evaluation, GST-pull down assays and co-immunoprecipitations to detect the interaction among NS1 and PSD-95. The outcomes showed that NS1 of avian influenza virus H5N1 (Achicken Guangdong12005) is able to bind to PSD-95, whereas NS1 of human influenza virus H1N1 (AShantou1692006) is unable to complete so. The results also revealed that NS1 of H5N1 substantially reduces the production of nitric oxide (NO) in rat hippocampal neurons. Conclusion: In summary, our study indicates that NS1 of influenza A virus can bind with neuronal PSD-95, along with the avian H5N1 and human H1N1 influenza A viruses possess distinct binding properties. Keyword phrases: NS1, PSD-95, influenza virus, nitric oxide, neuronsBackground Influenza virus nonstructural protein (NS1) is encoded by a co-linear mRNA and consists of 202-237 amino acids, based on the influenza A virus strains. The NS1 proteins contain an RNA-binding domain, an effector domain and an unstructured C-terminal domain around -20 amino acids long. The final four amino acids of the NS1 C-terminal compose the PDZ binding motif, which contributes towards the virulence of influenza A virus and A phosphodiesterase 5 Inhibitors Related Products modulate.
