Anti-STX3 antibodies are used in the immunodetection of the protein syntaxin 3. In humans, the canonical protein has a reported length of 289 amino acid residues and a mass of 33.2 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Syntaxin protein family, STX3 is suspected to be involved in docking of synaptic vesicles at presynaptic active zones. The STX3 gene has been associated with the disease, Retinal dystrophy and microvillus inclusion disease. Synonyms for this target antigen include MVID2, RDMVID, STX3A, syntaxin 3A, syntaxin 3B, and DIAR12. STX3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 60 citations in the literature describe the use of STX3 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
