The number of surface and synaptic GABA(A) receptors is an important determinant of inhibitory synapse strength. Surface receptor number is in part controlled by removal of receptors from the membrane by interaction with the clathrin adaptor AP2. Here we demonstrate that there are two binding sites for AP2 in the gamma2-subunit: a Yxxvarphi type motif specific to gamma2-subunits and a basic patch AP2 binding motif, that is also found in GABA(A) receptor beta-subunits. Blocking GABA(A) receptor-AP2 interactions using a peptide that inhibits AP2 binding to GABA(A) receptors via the conserved basic patch mechanism increases synaptic responses within minutes, whereas simultaneously blocking both binding mechanisms has an additive effect. These data suggest that multiple AP2 internalization signals control the levels of surface and synaptic GABA(A) receptors to regulate synaptic inhibition.
