Inhibitory synapses dampen neuronal activity through postsynaptic
hyperpolarization. The composition of the inhibitory postsynapse and the
mechanistic basis of its regulation, however, remain poorly understood. We used
an in vivo chemico-genetic proximity-labeling approach to discover inhibitory
postsynaptic proteins. Quantitative mass spectrometry not only recapitulated
known inhibitory postsynaptic proteins but also revealed a large network of new
proteins, many of which are either implicated in neurodevelopmental disorders or
are of unknown function. Clustered regularly interspaced short palindromic
repeats (CRISPR) depletion of one of these previously uncharacterized proteins,
InSyn1, led to decreased postsynaptic inhibitory sites, reduced the frequency of
miniature inhibitory currents, and increased excitability in the hippocampus. Our
findings uncover a rich and functionally diverse assemblage of previously unknown
proteins that regulate postsynaptic inhibition and might contribute to
developmental brain disorders.
