text_B: Collybistin is a protein identified as a regulator of the localization of gephyrin , inducing the formation of submembrane gephyrin aggregates that accumulate glycine and GABA receptors .. protein. protein. gephyrin. gephyrin. submembrane. submembrane. glycine. glycine receptor. GABA receptors. GABA receptors. In 2000 it was identified as a gephyrin binding partner , and an important determinant of inhibitory postsynaptic membrane formation and plasticity .. gephyrin. gephyrin. postsynaptic. postsynaptic. plasticity. Synaptic plasticity. Gephyrin and collybistin are recruited to developing postsynaptic membranes of inhibitory synapses by the trans-synaptic adhesion molecule neuroligin-2 , where they provide the scaffold for the clustering of inhibitory postsynaptic receptors to form a functioning inhibitory synapse .. postsynaptic. postsynaptic
