This study sought to explore phosphoproteome signaling dysregulation in different models of neurodegeneration. We collected phosphotyrosine, MAPK/CDK substrates, global phosphoproteome, and protein expression data from hippocampus and/or cortex tissue from each model. Tryptic peptides were multiplexd with TMT, enriched for phosphopeptides, and then identified and quantified by LC-MS/MS. We additionally quantified phosphotyrosine peptides from BV-2 cells expressing various Siglec receptor constructs.
