ABSTRACT
Objective:To express and purify the TRIM5? chimaera[TRIM5? H(R328-332)] protein and to explore the interaction between the TRIM5? H(R328-332)and HIV-1gag. Methods:The plasmid pET28aTRIM5? H(R328-332) was transformed to E.coli BL21 (DE3) strain ,and the expression of TRIM5? H(R328-332) protein was induced by IPTG,purified with Ni2+ chromatography.The expression and purification of TRIM5? H(R328-332) were analyzed by SDS-PAGE and Western blot,and the interaction between TRIM5? H(R328-332) and HIV-1gag was detected by co-immunoprecipitation,His pull-down and ELISA. Results:The recombinant plasmid pET28aTRIM5? H(R328-332) was successfully expressed in E.coli. The results showed that the purified full length TRIM5? H(R328-332) interacted with HIV-1gag protein. Conclusion:The human TRIM5? chimaera was expressed successfully in vitro,and the study demonstrates that the human TRIM5? chimaera interacts with HIV-1 gag in vitro.
