Anti-STXBP4 antibodies are used in the immunodetection of the protein syntaxin binding protein 4. In humans, the canonical protein has a reported length of 553 amino acid residues and a mass of 61.7 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. STXBP4 is reported to play a role in the translocation of transport vesicles from the cytoplasm to the plasma membrane. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include STX4-interacting protein and syntaxin 4 interacting protein. STXBP4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of STXBP4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
