A Role for Stargazin in Experience-Dependent Plasticity
During development, neurons are constantly refining their connections in response to changes in activity. Experience-dependent plasticity is a key form of synaptic plasticity, involving changes in α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid ...

Mechanism of Modulation of AMPA Receptors by Stargazin [PDF]
AMPA receptors (AMPARs) mediate most of the fast excitatory synaptic transmission in the brain. Native AMPARs typically form heterotetrameric complexes and associate with a variety of auxiliary subunits. Stargazin (gamma2) is the prototype and most studied member of the transmembrane AMPA receptor regulatory proteins family, and regulates several ...

Autoinactivation of the stargazin-AMPA receptor complex: subunit-dependency and independence from physical dissociation. [PDF]
Agonist responses and channel kinetics of native α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors are modulated by transmembrane accessory proteins.

Phosphorylation of Stargazin by Protein Kinase A Regulates Its Interaction with PSD-95 [PDF]
Stargazin is the first transmembrane protein known to associate with AMPA (alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate) glutamate receptors (AMPARs) and regulate their synaptic targeting by two distinct mechanisms, specifically via delivery of AMPARs to the surface membrane and synaptic targeting of these receptors by binding to PSD-95/SAP-90 ...

Reconstitution of invertebrate glutamate receptor function depends on stargazin-like proteins [PDF]
α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPARs) are a major subtype of ionotropic glutamate receptors (iGluRs) that mediate rapid excitatory synaptic transmission in the vertebrate brain. Putative AMPARs are also expressed in the nervous system of invertebrates.

Roles of stargazin and phosphorylation in the control of AMPA receptor subcellular distribution [PDF]
Understanding how the subcellular fate of newly synthesized AMPA receptors (AMPARs) is controlled is important for elucidating the mechanisms of neuronal function. We examined the effect of increased synthesis of AMPAR subunits on their subcellular distribution in rat hippocampal neurons. Virally expressed AMPAR subunits (GluR1 or GluR2) accumulated in

Further characterization of regulation of CaV2.2 by Stargazin [PDF]
Stargazin, a transmembrane protein expressed in the nervous system, shares similarities with the γ₁ subunit of skeletal muscle calcium channels. It was thus termed γ₂ subunit of neuronal calcium channels. Stargazin downregulates the expression of Ca(V)2 channels, however, its functional modulation of these channels remains debated.

Stargazin is an AMPA receptor auxiliary subunit [PDF]
AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors mediate fast excitatory synaptic transmission in brain and underlie aspects of synaptic plasticity. Numerous AMPA receptor-binding proteins have been implicated in AMPA receptor trafficking and anchoring.
