Figure Lengend Snippet: a Schematic of AKAP11 immunoprecipitation (IP) and its most notable, known interactors. b Immunoblot of AKAP11 in IPs of anti-AKAP11 and control IgG in 12-week-old (12wk) WT or Akap11 -/- cortical tissue. This experiment was repeated in >5 independent experiments, with similar results. c Volcano plot comparing Log Fold-Change (Log FC) against P value for AKAP11 IP in WT vs Akap11 -/- , displaying all proteins detected by coIP-MS. A moderated two-sample t-test was applied to the sample group datasets. Proteins that were enriched (red) by anti-AKAP11 IP from WT versus Akap11 -/- cortical extracts. Enriched proteins, defined by having a nominal P value < 0.05 and Log FC > 0, are colored red. Downregulated proteins are mostly antibody-related artifacts and can be found in Supplementary Data . d Venn diagram comparing previously published AKAP11 interactions with the brain interactome in this study. Full results are displayed in Supplementary Data . e Immunoblot of AKAP11, PKA subunits and control proteins, in IPs of AKAP11, GluA1 or IgG control in WT or Akap11 -/- cortical lysate. This experiment was repeated in >3 independent experiments, with similar results. f Immunoblot of AKAP11 in IPs of PKA subunits, in WT cortical lysates. This experiment was repeated in >2 independent experiments, with similar results. g–j Immunoblot with indicated antibodies, in IPs of anti-GSK3α, GSK3β, VAPA, VAPB, AKAP11, P62 or DYRK1a in WT or Akap11 -/- cortical lysate. These experiments were repeated in at least 2 independent experiments, with similar results. k Gene set enrichment analysis of all proteins displayed in 1c, showing selected gene ontologies with a positive normalized enrichment score (NES) and adjusted P -value (FDR) < 0.01. Redundant (similar) pathways were removed for clarity. The top most enriched proteins within each ontology are listed within the histograms. GSEA uses a Kolmogorov-Smirnov test, two tailed, with Benjamini-Hochberg (B-H) False Discovery Rate (FDR) correction applied.

Figure Lengend Snippet: a Number of phosphoproteins reaching a significance threshold of nominal P < 0.05. Fractions of upregulated and downregulated DAPPs are highlighted in red and blue, respectively. b Volcano plots of 12wk synapse phosphoproteomics data for Akap11 +/- and Akap11 -/- vs. WT controls. Phosphoproteomic measurements are normalized to MS-proteomics measurements from the same samples. Known PKA Cα substrates from PhosphoSitePlus are labeled green. AKAP11 phosphopeptides are omitted from Akap11 -/- plots, for clarity. a,b A moderated two-sample t-test was applied to the datasets to compare WT, Akap11 +/- and Akap11 -/- sample groups. c Motif analysis of peptides flanking the phosphorylation site of P < 0.05 phosphosites in A. n(fg) are the number of foreground peptides, and n(bg) are the number of background peptides. Red lines indicate FDR significance, calculated by log odds enrichment. d PTM-SEA of synapse phosphoproteomics data, using known kinase substrates from PhosphoSitePlus. Black borders indicate FDR significance. e ELISA-based PKA activity measurements comparing total lysate and synapse fractions of cortex (left) and striatum-enriched tissue (right). One Unit (U) is defined by the manufacturer as the quantity of PKA that catalyzes the transfer of 1.0 pmol phosphate from ATP to substrate. Two-way ANOVA with Tukey’s post hoc test. f Immunoblotting and quantification of AKAP11, PKA subunits, p-GluA1 S845 and GluA1 in 12wk cortical total lysate. One-way ANOVA with Tukey’s post hoc test. e,f Data are represented as mean ± SEM. See Supplementary Data for detailed statistical information.
