WebGephyrin has long been thought of as a master regulator for inhibitory synapses, acting as a scaffold to organize γ-aminobutyric acid type A receptors (GABAARs) at the post-synaptic density. Accordingly, gephyrin immunostaining has been used as an indicator of inhibitory synapses; despite this, the pan-synaptic localization of gephyrin to specific classes of … WebSimilarly, gephyrin knockout reduced GABA A R α2, α3, β2/3, and γ2 subunit clusters in the spinal cord. However, gephyrin deletion did not affect the clustering of α1 or α5 subunits in the spinal cord, a finding that suggested that GABA A Rs containing these subunits can cluster independently of gephyrin (Kneussel et al., 2001).
