The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.
Excitatory synapses that occur further away from the postsynaptic cell soma exhibit greater neurotransmitter release probability, which appears to improve signal transfer fidelity for high-frequency afferent firing.
Release site heterogeneity represents a previously unknown level of structural and functional organization within individual active zones in central synapses, which determines the spatiotemporal dynamics of multi-vesicular release.
Genetic and electrophysiological analyses reveal that the mechanisms orchestrating the induction and expression of homeostatic plasticity are compartmentalized and operate with exquisite specificity on both sides of the synapse.
Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.
