Abstract

The invention is suitable for the technical field of genetic engineering, and provides a target specific influenza A virus medicament screening yeast two-hybrid system and application thereof. The target specific influenza A virus medicament screening yeast two-hybrid system comprises an influenza A virus PB1gene and an influenza A virus gene, a PB1 gene and a PA gene, and PB1, PB2 and PA genes. The target specific influenza A virus medicament screening yeast two-hybrid system for medicament screening has the advantages of high specificity, high throughput screening and exact mechanism of a target medicament.

Description

Technical field [0001] The invention belongs to the technical field of genetic engineering, and particularly relates to a yeast two-hybrid system, system and application for screening of target-specific influenza A virus drugs. Background technique [0002] Influenza viruses belong to the Orthomyxoviridae family (Orthomyxoviridae). They are enveloped negative-strand RNA viruses. The members include influenza A, B, and C influenza viruses. At present, influenza A and B viruses are the main infections in humans. The genomes of influenza A and B viruses contain 8 segments, which are single-stranded and negative-stranded RNAs, each encoding at least 10 proteins. According to the antigenic properties of hemagglutinin (HA) and neuraminidase (NA) on the surface of the virus, influenza A viruses can be divided into 1-16 HA subtypes and 1-9 NA subtypes. At present, the influenza viruses that cause human infection are mainly H1 (N1), H3 (N2) subtypes and type B influenza viruses. Influen...
