摘要

通过探究鸡腺苷琥珀酸裂解酶(adenylosuccinate lyase)基因ADSL与其互作基因的调控关系,为进一步研究ADSL在肌肉中高表达的原因和ADSL影响肌肉风味的机制提供参考.本研究构建了鸡(gallus)ADSL基因的重组真核表达载体pEGFP-C1-ADSL,将pEGFP-C1-ADSL和pEGFP-C1 质粒分别转染鸡成肌细胞,提取表达成功的细胞总蛋白,利用免疫共沉淀(co-immunoprecipitation,Co-IP)联合质谱分析鉴定与鸡ADSL蛋白互作的细胞蛋白,并对结果进行GO功能注释、KEGG通路和蛋白互作网络分析.通过分析筛选出RPL4、PD-LIM5、ACTG1 和SRSF10 蛋白,检测在ADSL基因过表达和沉默状态下,RPL4、PDLIM5、ACTG1 和SRSF10 基因在成肌细胞中的表达情况.结果表明,与ADSL互作的蛋白共 94 个;生物信息学分析表明,这些蛋白定位于细胞结构体、胞内和含蛋白质的复合物上,它们主要参与细胞进程、生物调节和刺激反应等生物进程.间接免疫荧光结果显示,重组蛋白pEGFP-C1-ADSL主要定位于细胞核和细胞质.ADSL过表达时,成肌细胞内RPL4 基因和PDLIM5 基因的表达下调,ACTG1 和SRSF10 基因的表达上调;当ADSL被沉默后,成肌细胞内RPL4 和ACTG1 基因的表达上调.研究结果丰富了调控风味的ADSL蛋白,为进一步了解ADSL的功能及该基因在肌肉中高表达提供了参考.

Abstract

By exploring the regulatory relationship between chicken adenylosuccinate lyase gene ADSL and its inter-action genes,to provide reference for further study on the reason of high expression of ADSL in muscle and the mech-anism of ADSL affecting muscle flavor.In this study,the recombinant eukaryotic expression vector pEGFP-C1-ADSL was constructed.The pEGFP-C1-ADSL and pEGFP-C1 plasmids were transfected into chicken myoblasts respective-ly,and the total protein of the successfully expressed cells was extracted.The cellular proteins interacting with chicken ADSL protein were identified by co-immunoprecipitation(Co-IP)combined with mass spectrometry,and the results were analyzed by GO functional annotation,KEGG pathway and protein interaction network.RPL4,PD-LIM5,ACTG1 and SRSF10 were screened,and the expression of RPL4,PDLIM5,ACTG1 and SRSF10 genes in myoblasts were detected under overexpression and silencing of ADSL gene.The results showed that 94 proteins inter-acted with ADSL.Bioinformatics analysis showed that these proteins were localized to cellular anatomical entity,in-tracellular and protein-containing complexs,and they were mainly involved in biological processes such as cellular processes,biological regulation,and stimulus responses.The results of indirect immunofluorescence showed that the recombinant protein pEGFP-C1-ADSL was mainly localized in the nucleus and cytoplasm.When ADSL was overex-pressed,the expression of RPL4 and PDLIM5 genes in myoblasts was down-regulated,and the expression of ACTG1 and SRSF10 genes was up-regulated.When ADSL was silenced,the expression of RPL4 and ACTG1 genes in myo-blasts was up-regulated.The results enriched the ADSL protein that regulates flavor,and provided a reference for further understanding the function of ADSL and the high expression of this gene in muscle.
