GRAPHICAL ABSTRACT

Sunburst plot from SynGO analysis of M6a’s potential synaptic interactors (https://www.syngoportal.org/, Koopmans et al., 2019). This work shows a combination of co-immunoprecipitation assay with quantitative tandem mass tag spectrometry (TMT/MS) to identify potential protein-protein interactions. Using a chimera protein that only contains the extracellular loops of neuronal glycoprotein M6a, we performed a co-IP with rat hippocampi samples followed by TMT/MS. Data analysis revealed 72 potential interactors of M6a’s loops, 45 of which are related to synapse localization.
