AMPA ion channels undergo phosphorylation, which may affect synaptic plasticity and is tightly regulated by phos-phokinases such as PKA, PKC, CaMKII, and others. Phosphorylation generally potentiates AMPA receptor activation, with evidence that it occurs by keeping the channel open longer or more often. AMPA receptors also contain 4 to 6 N-glycosylation sites that influence binding of ligands to the receptor pocket, with effects that depend on the type of ligand and the subunit's flip/flop specification.
