GLT-1 is a crucial membrane-bound protein in the brain, primarily responsible for clearing the excitatory neurotransmitter glutamate from the extracellular space at synapses. This rapid removal is essential for terminating the postsynaptic action of glutamate and maintaining glutamate homeostasis.SLC1A2 / EAAT2 / GLT-1
The term "glt1 peptide" most commonly appears in scientific research contexts, particularly in the development and use of antibodies and blocking peptides for studying GLT-1.2025年11月25日—Authors demonstrated that the upregulation ofGLT1corrected Purkinje cell firing and motor incoordination in myotonic dystrophy. This study ... These peptides are often synthesized to target specific regions of the GLT-1 protein, such as its extracellular or C-terminal domains. Researchers utilize these peptides in various applications, including Western blot analysis, ELISA, and as reagents to validate antibody specificity. For instance, a blocking peptide can be used to confirm that an antibody specifically recognizes the GLT-1 protein by preventing the antibody from binding to its target.
GLT-1 (encoded by the SLC1A2 gene) is predominantly expressed in astrocytes and Bergmann glia, playing a vital role in neuronal function and preventing excitotoxicity, a condition where excessive glutamate can damage nerve cellsAnti-Glutamate Transporter EAAT2 (GLT1). Its function is so critical that disruptions in GLT-1 activity are implicated in various neurological disorders.
The peptides associated with GLT-1 are typically short chains of amino acids that mimic a portion of the GLT-1 proteinGLP-1 Agonists. These can be used in several ways:
* Antibody Production: Synthetic peptides corresponding to specific GLT-1 sequences are often used as immunogens to generate polyclonal antibodies against the transporterTransports L-glutamate and also L- and D-aspartate. Essential for terminating the postsynaptic action of glutamate by rapidly removing released glutamate .... These antibodies are invaluable tools for researchers investigating GLT-1 expression, localization, and function.作者：A Schmitt·1996·被引用次数：172—The study showed thatGLT1 was expressed in astrocytes and Bergmann gliawhich were identified by the detection of an astrocytic marker protein. Additionally, ... For example, an anti-GLT-1 antibody might be raised against a peptide sequence found within the C-terminal region of the protein.Conformational Changes Monitored on the Glutamate ...
* Blocking Peptides: Researchers may use a specific peptide that corresponds to the epitope recognized by an antibodyTransports L-glutamate and also L- and D-aspartate. Essential for terminating the postsynaptic action of glutamate by rapidly removing released glutamate .... This blocking peptide can be added to an experiment to compete with the antibody for binding to the target protein. If the antibody's signal is abolished or reduced in the presence of the blocking peptide, it strongly suggests that the antibody is indeed specific to GLT-1. Some EAAT2/GLT-1 (extracellular) blocking peptides are available for this purpose.
* Research Tools: Beyond antibody validation, specialized GLT-1 peptides might be designed to investigate protein-protein interactions or functional domains of the transporter. For instance, studies have explored interactions between GLT-1 and other proteins like PS1/gamma-secretase, where specific GLT-1 residues within transmembrane domains (TM5) are crucial for binding作者：A Kiryk·2008·被引用次数：69—GLT1is one of the major transporters responsible for maintenance of glutamate homeostasis in the brain. In the present study, ....
While many GLT-1 peptides are research reagents, the availability of specific blocking peptides can vary. Some products, like certain anti-glutamate transporter GLT-1 blocking peptides, have been withdrawn from sale for commercial reasonsRecombinant Human EAAT2/GLT1 GST (N-Term) Protein. However, research-grade GLT-1 peptides and related antibodies are generally available from scientific supply companies.
It is important to distinguish GLT-1 from other entities that share similar acronyms. For example, GLP-1 agonists are a class of medications used to manage blood sugar in Type 2 diabetes and obesity, and they are unrelated to the glutamate transporter GLT-1.Anti-Glutamate Transporter Antibody, Glial | AB1783 Similarly, "Glutamate synthase 1" (also abbreviated as GLT1 in some contexts) is involved in glutamate biosynthesis, a different metabolic pathwayThe Glutamate Transporter GLT1a Is Expressed in ....
In summary, the glt1 peptide is a scientific tool derived from or mimicking the GLT-1 glutamate transporter. These peptides are primarily used in immunological assays and molecular biology research to study the critical role of GLT-1 in maintaining brain health and function.
