SARS-CoV N蛋白可与病毒RNA形成复合物,也可与病毒或宿主细胞中多种蛋白质相互作用,影响宿主细胞的多个信号转导通路,干扰宿主细胞的细胞周期,从而改变宿主细胞的生命活动.利用酵母双杂交技术筛选了15个宿主细胞内与SARS-CoV N蛋白的相互作用蛋白,其中包括信号传导组分7种,蛋白激酶3种,细胞因子2种,未知功能蛋白3种.并利用免疫共沉淀方法进一步证实了趋化因子CXCL16是宿主细胞与SARS-CoV核衣壳蛋白的相互作用蛋白.
15 SARS-CoV N Protein Interacting Protein (NPIP) were selected from host cells using Yeast Two-hybrid system (Y2H). These are Angiogenin, acyglycerol kinase, cytochrome oxydase subunit I, CXC chemokine ligand 16, epidermal growth factor receptor pathway substrate 15, glutathione S-transferase kappa 1,integrin beta 1, jun oncogene, NIMA (never in mitosis gene a)-related kinase 10, protein tyrosine kinase 2 beta,homo sapiens SH3KBP1 binding protein 1 and ubiquitin specific peptidase 53. With the aid of immunological co-precipitation (CO-IP), it was confirmed that chemokine CXCL16 was the interactor with SARS-CoV N protein in host cells.
