This figure summarizes major adhesion molecules and scaffold/adaptor proteins at excitatory and inhibitory synapses. At excitatory synapses (left), presynaptic Neurexin1 binds postsynaptic Neuroligin1, with PSD-95 as a central scaffold; Cadm1 contributes to spine formation and synapse stabilization. At inhibitory synapses (right), postsynaptic Neuroligin2 organizes an inhibitory scaffold centered on Gephyrin. Balanced excitatory and inhibitory synaptic organization is essential for normal circuit function and plasticity, and its disruption is implicated in neurological disorders. The presynaptic scaffold/adaptor complex includes CASK, Mint, and other synaptic organizing molecules. In contrast, cytoskeletal adaptor/structural proteins at presynaptic sites include Ankyrin-G, Spectrin, F-actin, and actin-associated protains.
