GST-HDAC4融合蛋白载体的构建及其蛋白表达
Construction of GST-HDAC4 Fusion Protein Vector and Its Protein Expression
摘要
Abstract
Objective To construct the prokaryotic expression vector of human HDAC4 protein and glutathione-S-transferase (GST) for protein expression and purification. Methods pcDNA3.1-HDAC4 was digested by EcoR I ,the hHDAC4 coding sequence was obtained and cloned into prokaryotic expression vector pGEX-5X-1 to generate novel vector GST-HDAC4. After identification of GST-HDAC4, Escherichia coli BL21 was transformed and induced by isopropyl-β-D-thiogalactoside (IPTG),and target protein was obtained after purification. The expression of the recombinant plasmid was proved by Western blot. Results Restriction enzyme digestion and sequencing indicated that prokaryotic expression vector of GST-HDAC4 fusion protein was successfully constructed. Coomassie brilliant blue staining and Western blot revealed that GST-HDAC4 fusion protein with bioactivity was successfully obtained. Conclusion The prokaryotic expression vector of HDAC4 was successfully constructed. The fusion protein of GST-HDAC4 with bioactivity has been obtained.关键词
