General description

Syntaxin-binding protein 1 (STXBP1) belongs to the Sec1/Munc-18 (SM) family of proteins. It is an intracellular protein present in presynaptic terminals.

Immunogen

Syntaxin-binding protein 1 recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

Syntaxin-binding protein 1 (STXBP1) is required for secretion of neurotransmitters and for vesicle fusion in eukaryotic cells. In neurons, Mint 1 and 2 proteins bind to STXBP1 to form the essential synaptic vesicle fusion machinery and help in regulated exocytosis. It also forms a tight complex with the Soluble NSF attachment protein receptor (SNARE) syntaxin 1, in which syntaxin is held in a closed conformation and further stabilized to form the SNARE complexes. This shows that STXBP1 allows the formation of a complex between syntaxin and Synaptosomal-Associated Protein 25kDa (SNAP-25), which in turn functions as an acceptor for vesicle-bound synaptobrevin. All these activities are essential intermediates in the pathway towards exocytosis.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
