abstract = {To understand how cells communicate with each other, it is
essential to define the cellular secretome, a collection of
proteins including soluble secreted, unconventionally
secreted and proteolytically-shed proteins. Quantitative
methodologies to decipher the secretome are challenging, due
to the requirement of large cell numbers and abundant serum
proteins that interfere with the detection of low-abundant
cellular secretome proteins. Here, we miniaturized secretome
analysis by developing the improved
secretome-protein-enrichment-with-click-sugars method
(iSPECS), which identifies the glyco-secretome. We applied
this method to provide a cell type-resolved mouse brain
glyco-secretome resource. Our data show that a surprisingly
high number of secreted proteins are generated by ectodomain
shedding in a cell type-specific manner. Two examples are
neuronally secreted ADAM22 and CD200, which we identified as
new substrates of the Alzheimer-linked protease BACE1. Taken
together, iSPECS and the brain glyco-secretome resource can
be exploited for a wide range of applications to study
protein secretion and shedding.},
