a Male C57Bl/6 N mice administered with adeno-associated viruses expressing a microRNA to silence Sec22b (miR-Sec22b) with re-expressing of Sec22b cDNA (Sec22b-WT or Sec22b-S137A) or a AAV control (miR-NC & Gfp). The mice were acutely treated with either saline (VEH) or acyl-glucagon (GCG) (n = 3/group). Co-immunoprecipitation proteomics analysis of the liver lysates was then conducted. VENN diagram summarizes the amount of proteins interacting with SEC22B under the different conditions (enriched proteins: Log2 > 4, FDR < 0.05). b Functional enrichment analysis of 20 proteins which exclusively bounded with SEC22B (in Sec22b-WT + Glucagon group). c Gene ontology enrichment analysis of glucagon induced proteins bound with SEC22B-WT protein (Sec22b-WT + GCG/Sec22b-WT + VEH). d Gene ontology enrichment analysis of glucagon induced proteins bound with SEC22B-S137A mutant proteins (Sec22b-S137A + GCG/Sec22b-WT + VEH). For enrichment analysis, g:GOSt tool was used on the gProfiler web server to perform functional enrichment. g:GOSt utilizes Fisher’s one-tailed test and applies multiple testing correction by default.
