abstract = {The β-secretase BACE1 has become a prime target in
Alzheimer’s disease (AD) therapy, because it drives the
production of pathogenic amyloid β peptides. However,
clinical trials with BACE1-targeting drugs were halted due
to adverse effects on cognitive performance. We propose here
that cognitive impairment by BACE1 inhibitors may be a
corollary of a higher function of BACE1 related to proper
sleep regulation. To address non-enzymatic effects of BACE1
on ion channels likely involved in the sleep–wake cycle,
we analyzed sleep patterns in both BACE1-KO mice and a newly
generated transgenic line expressing a proteolysis-deficient
BACE1 variant (BACE1-KI). To investigate changes in the
cellular proteome as well as the secretome, primary neurons
were metabolically labeled with ManNAz and the secretome was
anlyzed using the hiSPECS method. The results showed
areduction of several BACE1 substrates in the secretome
(i.e. SEZ6, APLP1) as well as an accumulation of some BACE1
substrates in the lysate (i.e. APLP1, SEZ6, CNTN2).},
