Özet

Influenza A viruses are enveloped viruses classified in Orthomyxoviridae family. These viruses have a genome composed of

eight single-stranded, negative sense RNA molecules. NS1 protein, which is the subject of this work, is encoded on the eighth

segment, the smallest segment of the viral genome. It is known that one of the most important functions of the NS1 protein

is to block the host interferon defense mechanisms. In this work, it was aimed to detect of the host cellular proteins related

with influenza virus NS1 protein by using yeast two-hybrid method. Human and avian influenza A virus NS1 protein was used

as a bait and assayed for interaction with the proteins encoded by cDNAs of HEK293 cells. Fourteen candidate genes that may

be related with the NS1 protein were determined. Among these genes, the full length sequence of PSMB4 and EEF1G gene

were cloned in pCHA, a mammalian expression vector, to use in research that carried out with mammalian cells in future. The

other candidate genes were named as NKG1 - NKGn. How the specified candidate proteins interact with NS1 protein and how

effect influenza virus replication were not been evaluated within the scope of this work. Elucidation of the action mechanisms

of these proteins require detailed studies on each candidate protein, one by one. Data obtained in this works will be base for

fighting against viral pathogens.
