Superactivation of AMPA receptors by auxiliary proteins
Glutamate receptors form complexes in the brain with auxiliary proteins, which control their activity during fast synaptic transmission through a seemingly bewildering array of effects. Here we devise a way to isolate the activation of complexes using polyamines, which enables us to show that transmembrane AMPA receptor regulatory proteins (TARPs) exert their effects principally on the channel ...
متن کاملCortical development of AMPA receptor trafficking proteins
AMPA-receptor trafficking plays a central role in excitatory plasticity, especially during development. Changes in the number of AMPA receptors and time spent at the synaptic surface are important factors of plasticity that directly affect long-term potentiation (LTP), long-term depression (LTD), synaptic scaling, and the excitatory-inhibitory (E/I) balance in the developing cortex. Experience-...
متن کاملPICK1 mediates transient synaptic expression of GluA2-lacking AMPA receptors during glycine-induced AMPA receptor trafficking.
The number and subunit composition of postsynaptic AMPA receptors (AMPARs) is a key determinant of synaptic transmission. The vast majority of AMPARs contain GluA2 subunit, which renders the channel impermeable to calcium. However, a small proportion are GluA2 lacking and therefore calcium permeable (CP-AMPARs). It has been proposed recently that long-term potentiation (LTP) involves not only a...
متن کاملPhotoinactivation of Native AMPA Receptors Reveals Their Real-Time Trafficking
AMPA receptors mediate the majority of the fast excitatory transmission in the central nervous system. Much evidence suggests that the fast trafficking of AMPA receptors into and out of the postsynaptic membrane underlies changes in synaptic strength thought to be necessary for higher cognitive functions such as learning and memory. Despite the abundance of research conducted in this area, a di...
متن کاملDifferences in AMPA and kainate receptor interactomes facilitate identification of AMPA receptor auxiliary subunit GSG1L.
AMPA receptor (AMPA-R) complexes consist of channel-forming subunits, GluA1-4, and auxiliary proteins, including TARPs, CNIHs, synDIG1, and CKAMP44, which can modulate AMPA-R function in specific ways. The combinatorial effects of four GluA subunits binding to various auxiliary subunits amplify the functional diversity of AMPA-Rs. The significance and magnitude of molecular diversity, however, ...
