WebGABA A receptors are associated with both protein kinase C βII and RACK1 (receptor for activated C kinase) that together mediates phosphorylation of β receptor subunits, thereby facilitating trafficking and functional modulation of GABA A receptors. GABA A receptors also undergo dynamin-dependent, clathrin-mediated endocytosis. 127 Webby interacting with the GABA A receptor on these cells. The GABA A receptor is a channel-forming protein that allows the passage of chloride ions into the cells. Excessive GABA A activation may play a role in mediat-ing the sedative effects of alcohol and other sedating and anesthetic agents. For example, alcohol enhances the GABA
