Co-IP/MS was used to predict the proteins that might interact with PGRP-S. (A) Proteins were extracted by lysis buffer from SMMC 7721 cells. Eluted proteins immunoprecipitated by anti-PGRP-S or control immunoglobulin G (IgG) were stained with Coomassie brilliant blue. (B) Co-IP/MS analysis identified 843 potential interacting proteins that were different from IgG. (C) GO analysis for PGRP-S potential binding protein. The ordinate represents the GO function name, and the abscissa represents the P-value of enrichment significance. Green bars represent biological processes, red bars represent cellular components, and blue bars represent molecular functions. (D) KEGG pathway analysis for PGRP-S potential binding protein (www.kegg.jp/kegg/kegg1.html). The ordinate is KEGG pathway name and the abscissa is P-value.
