Gephyrin (GPHN) is a multifunctional scaffolding protein that plays a central role in the organization of inhibitory synapses within the central nervous system. It is essential for the clustering and stabilization of inhibitory neurotransmitter receptors, particularly glycine receptors and GABA(A) receptors, at postsynaptic membranes. Through these interactions, Gephyrin regulates inhibitory synaptic transmission and contributes to maintenance of neuronal excitability and synaptic balance.
Gephyrin antibody, also referred to as GPHN antibody and Gephyrin synaptic scaffold antibody in the literature, recognizes a cytoplasmic protein that is highly enriched at inhibitory postsynaptic sites. Gephyrin forms lattice-like assemblies beneath the postsynaptic membrane, where it anchors receptor complexes and coordinates synaptic organization. This structural role makes Gephyrin one of the most widely used markers for identifying inhibitory synapses and studying receptor clustering dynamics in neuronal systems.
This Gephyrin Antibody / Inhibitory Synapse and Receptor Clustering Marker Antibody is uniquely positioned for studies of inhibitory neurotransmission and synaptic organization. Gephyrin-mediated receptor clustering is critical for efficient inhibitory signaling and proper neural circuit function. Alterations in Gephyrin distribution or expression have been associated with disrupted synaptic architecture and abnormal inhibitory signaling in neurological disease models. As a result, Gephyrin serves as an important marker for evaluating inhibitory synapse integrity and postsynaptic specialization.
Gephyrin plays a critical role in maintaining inhibitory synaptic strength through stabilization and trafficking of GABA(A) and glycine receptor complexes at postsynaptic membranes. Dynamic remodeling of Gephyrin clusters contributes to synaptic plasticity and regulation of inhibitory neurotransmission in response to neuronal activity. Because inhibitory signaling is essential for maintaining excitatory-inhibitory balance within neural circuits, alterations in Gephyrin organization can influence neuronal network stability and synaptic responsiveness.
Disruption of Gephyrin expression or receptor clustering has been associated with multiple neurological and neurodevelopmental disorders involving altered inhibitory signaling. Changes in Gephyrin-dependent synaptic organization have been investigated in epilepsy, schizophrenia, autism spectrum disorders, and hyperekplexia models, highlighting the importance of inhibitory postsynaptic scaffold proteins in neural circuit regulation and disease-associated synaptic dysfunction.
In immunofluorescence and tissue-based analyses, Gephyrin is typically observed as punctate cytoplasmic staining associated with inhibitory postsynaptic structures, consistent with its role in receptor anchoring and synaptic scaffold formation. In western blot analysis, Gephyrin is detected as a protein corresponding to its expected molecular weight in neuronal and brain-derived samples. These expression patterns support its use in studies examining synaptic distribution, neuronal connectivity, and inhibitory signaling networks.
This rabbit polyclonal antibody is designed to detect Gephyrin with consistent performance in research applications. A Gephyrin antibody is suitable for detecting GPHN expression in studies of inhibitory synapse biology, receptor clustering, and neuronal signaling where synaptic scaffold proteins are of interest.
This antibody is part of a broader antibody panel offered by NSJ Bioreagents.
Optimal dilution of the Gephyrin Antibody / Inhibitory Synapse and Receptor Clustering Marker Antibody should be determined by the researcher.
An E. coli-derived human protein (amino acids K148-L736) was used as the immunogen for the Gephyrin antibody.
After reconstitution, the Gephyrin antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
