Abstract:

By exploring the regulatory relationship between chicken adenylosuccinate lyase gene ADSL and its interaction genes, to provide reference for further study on the reason of high expression of ADSL in muscle and the mechanism 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 respectively, 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, PDLIM5, 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 interacted with ADSL. Bioinformatics analysis showed that these proteins were localized to cellular anatomical entity, intracellular 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 overexpressed, 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 myoblasts 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.
