Stargazin promotes closure of the AMPA receptor ligand-binding domain [PDF]

Journal of General Physiology, 2014
Transmembrane AMPA receptor (AMPAR) regulatory proteins (TARPs) markedly enhance AMPAR function, altering ligand efficacy and receptor gating kinetics and thereby shaping the postsynaptic response. The structural mechanism underlying TARP effects on gating, however, is unknown.

The synaptic vesicle cluster as a controller of pre‐ and postsynaptic structure and function

The Journal of Physiology, Volume 603, Issue 20, Page 5935-5964, October 15, 2025.
Abstract figure legend The synaptic vesicle cluster acts as a master regulator of synaptic structure and function, through various involvements in processes that range from synaptic initiation to plasticity and synaptic loss. Abstract The synaptic vesicle cluster (SVC) is an essential component of chemical synapses, which provides neurotransmitter ...

Metabolic etiologies in West syndrome

Epilepsia Open, Volume 3, Issue 2, Page 134-166, June 2018., 2018
Summary West syndrome (WS) is an early life epileptic encephalopathy associated with infantile spasms, interictal electroencephalography (EEG) abnormalities including high amplitude, disorganized background with multifocal epileptic spikes (hypsarrhythmia), and often neurodevelopmental impairments.

Lengthening of the Stargazin Cytoplasmic Tail Increases Synaptic Transmission by Promoting Interaction to Deeper Domains of PSD-95 [PDF]

, 2015
SummaryPSD-95 is a prominent organizer of the postsynaptic density (PSD) that can present a filamentous orientation perpendicular to the plasma membrane.

Phosphorylation‐regulated phase separation of syndecan‐4 and syntenin promotes the biogenesis of exosomes

Cell Proliferation, Volume 57, Issue 10, October 2024.
This research uncovers a novel phosphorylation‐regulated phase separation property of SDC4 on the PM by which SDC4 realizes efficient recruitment of cytosolic syntenin and thereby facilitates the biogenesis of exosomes, providing potential intervention targets for exosome‐involved biomedical events. Abstract The biogenesis of exosomes that mediate cell‐

The Stargazin C Terminus Encodes an Intrinsic and Transferable Membrane Sorting Signal [PDF]

Journal of Biological Chemistry, 2008
Activity-dependent plasticity of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptors is regulated by their auxiliary subunit, stargazin. Association with stargazin enhances alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor surface expression and modifies the receptor's biophysical properties.

Identification of immune infiltration and PANoptosis‐related molecular clusters and predictive model in Alzheimer's disease based on transcriptome analysis

Ibrain, Volume 10, Issue 3, Page 323-344, Fall 2024.
Based on R, immune infiltration analysis found that normal and disease immune cells expressed differently, weighted gene co‐expression network analysis determined the key genes of diseases and clustering, and eXtreme Gradient Boosting model screened Hub genes. Abstract This study aims to explore the expression profile of PANoptosis‐related genes (PRGs)

Advances in understanding the pathogenesis of epilepsy: Unraveling the molecular mechanisms

Health Science Reports, Volume 7, Issue 2, February 2024.
Abstract Introduction Epilepsy is characterized by having two or more unprovoked seizures. Understanding the pathogenesis of epilepsy, requires deep investigation into the molecular mechanisms. This helps develop diagnostic techniques, treatments, and pharmacotherapy. It also enhances precision medicine and individualized treatment processes.

Transmembrane α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor regulatory protein expression during the development of absence seizures in genetic absence epilepsy rats from Strasbourg

Epilepsia, Volume 65, Issue 2, Page e20-e26, February 2024.
Abstract The transmembrane α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor (AMPAR) regulatory proteins (TARPs), γ2 (stargazin), γ3, γ4, γ5, γ7, and γ8, are a family of proteins that regulate AMPAR trafficking, expression, and biophysical properties that could have a role in the development of absence seizures.
