Anti-STXBP3 antibodies are used in the immunodetection of the protein syntaxin binding protein 3. In humans, the canonical protein has a reported length of 592 amino acid residues and a mass of 67.8 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is notably expressed in many tissues, such as the appendix and cerebral cortex. A member of the STXBP/unc-18/SEC1 protein family, STXBP3 is known to be involved with brain development and carbohydrate metabolism and homeostasis. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include MUNC18C, PSP, UNC-18C, platelet Sec1 protein, protein unc-18 homolog 3, and MUNC18-3. STXBP3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some STXBP3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
