Background: The protease BACE2 regulates (cid:1) -cell function by acting on an unknown substrate repertoire. Results: Analysis of the islet (cid:1) -cell sheddome reveals novel BACE2 and BACE1 targets. Conclusion: BACE2 and its homologue BACE1 target a diverse substrate repertoire, but naturally only share a small set of substrates. Significance: The identification of BACE2 and 1 substrates is crucial for understanding pancreatic (cid:1) -cell function. processtocompensateforincreasedinsulindemand.Deficiency a systematic and quantitative proteomic analysis to map the natural substrate repertoire of BACE2 and its homologue BACE1 in (cid:1) -cells. Loss- and gain-of-function studies of in vitro and in vivo models identified specific and functionally heterogeneous targets. Our analysis revealed non-redundant roles of BACE1/2 in ectodomain shedding with BACE1 regulating a broader and BACE2 a more distinct set of (cid:1) -cell-enriched substrates including two proteins of the seizure 6 protein family (SEZ6LandSEZ6L2).Lastly,ourstudyprovidesinsightsintothe global (cid:1) -cell sheddome and secretome, an important prerequi-site to uncover novel mechanisms contributing to (cid:1) -cell home-ostasis and a resource for therapeutic target and biomarker discoveries.
