Abstract:
Protein protein binding is the basis of virus and host cell interactions. With the application of technology of studying of protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) could be acquired. Non structure protein NS5A is one of the important regulatory factors in virus replication , transcription and signal transduction, but there are controversy in effect on HCV pathogenesis and resistance to interferon ?(IFN?). In order to describe the relationship between NS5A and host proteins, we use yeast two hybrid system 3 to screen the gene encoding proteins that could interact with NS5A from human hepatocyte library. Thirty five clones were obtained including apo A1, apo A2, apo B100, haplotype mitochondrion complete genome, phosphatidic acid phosphatase type 2B, albumin similar to tumor endothelial marker 5 precursor, matrix metalloproteinase 14, and three of the Homo sapiens hypothetical proteins. The study paved a way for further studies on the pathogenesis of HCV NS5A
