Stargazin Dephosphorylation Mediates Homeostatic Synaptic Downscaling of Excitatory Synapses [PDF]
Synaptic scaling is a form of homeostatic plasticity that is critical for maintaining neuronal activity within a dynamic range, and which alters synaptic strength through changes in postsynaptic AMPA-type glutamate receptors.

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 ...

Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously

Differences in Src phosphorylation of PSD-93 and PSD-95 drive differences in scaffolding activity. [PDF]
Abstract Scaffold proteins contain multiple binding modules that allow for co‐localization of proteins that lack a direct interaction. Evolution resulted in different combinations of binding modules that rewired existing signal transduction pathways.

Notes on the History of In Vitro Hippocampal Electrophysiology and LTP: Personal Reflections. [PDF]
ABSTRACT This essay describes the development of the in vitro hippocampal slice technique and my small contributions to it and to influencing Roger Nicoll's early interests in the hippocampus and LTP. My Ph.D. work at Harvard with Timothy Teyler was on field potential studies of synaptic plasticity, including LTP, in the rat in vitro hippocampal slice.

Molecular physiology of Arc/Arg3.1: The oligomeric state hypothesis of synaptic plasticity. [PDF]
Abstract The immediate early gene, Arc, is a pivotal regulator of synaptic plasticity, memory, and cognitive flexibility. But what is Arc protein? How does it work? Inside the neuron, Arc is a protein interaction hub and dynamic regulator of intra‐cellular signaling in synaptic plasticity.

Compensatory Interplay Between Clarin-1 and Clarin-2 Deafness-Associated Proteins Governs Phenotypic Variability in Hearing. [PDF]
Functional compensation between clarin‐1 and clarin‐2 in cochlear hair cells. Hearing loss associated with CLRN1 mutations shows striking phenotypic variability; however, the underlying mechanisms remain poorly understood. This study reveals that clarin‐1 and clarin‐2 function cooperatively in cochlear hair cells to sustain mechanoelectrical ...

Summary: Postsynaptic density protein 95 is a key scaffolding protein in the postsynaptic density of excitatory glutamatergic neurons, organizing signaling complexes primarily via its three PSD-95/Discs-large/Zona occludens domains.

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.

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.
