Protein components of a rat brain synaptic junctional protein preparation.
Antisera against a rat brain synaptic protein preparation, the postsynaptic density (PSD) fraction, were used to isolate cDNA clones by expression screening of a rat brain cDNA library. About one fifth of more than 200 analyzed cDNAs encoding potential synapse-associated proteins were previously unknown. Identifiable proteins include, among others, components of the pre- and postsynaptic cytoskeleton, synaptic vesicle proteins and several protein kinases and kinase substrates. This demonstrates that both pre- and postsynaptic elements purify with the PSD fraction.
