AMPA Receptor

The amino-hydroxy-methyl-isoxazolepropionic acid (AMPA) receptor is the most common glutamate receptor. It is an ionotropic transmembrane receptor that fluxes sodium, potassium, and calcium (if it lacks the GluR2 subunit).

Roles in Plasticity
AMPARs are highly regulated during ubiquitous synaptic plasticity processes, including canonical hippocampal LTP. AMPARs are also regulated by homeostatic plasticity, which depends on the presence of the GluR2 receptor.[citation]
