早幼粒细胞白血病蛋白与TAK1结合蛋白相互作用的生物信息学分析与验证
Bioinformatics analysis and validation of the interaction between PML protein and TAB1 protein
摘要
Abstract
Objective To analyze the interaction between PML protein and TAB1 protein using bioinformatic approaches and experimentally verify the results.Methods Using Rosetta software,a 3D model of TAB1 protein was constructed through a comparative modeling approach;the secondary structure of PML protein was retrieved in the PDB database and its crystal structure and 3D structure were resolved.Zdock 3.0.2 software was used to perform protein-protein docking of PML and TAB1,and the best conformation was extracted for molecular structure analysis of the docking model.The interaction between the two proteins was detected using immunoprecipitation in α-MMC-treated M1 inflammatory macrophages.Results When 6IMQ of PML was used as the docking site,PML protein formed 3 salt bridges,6 hydrogen bonds and 6 hydrophobic interactions with TAB1 proteins;when 5YUF of PML was used as the docking site,PML protein formed 1 hydrogen bond,3 electrostatic interactions and 9 hydrophobic interactions with TAB1 proteins,and both of the docking modes formed good molecular docking and interactions.In the M1 inflammatory macrophages treated with α-MMC for 4 h,positive protein bands of PML and TAB1 were detected in the cell lysates in PML-IP group.Conclusion PML protein can interact strongly with TAB1 protein.关键词
