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). WebCurrent research indicates that postsynaptic gephyrin clusters are dynamic assemblies that are held together and regulated by multiple protein-protein interactions.
