Anti-ST3GAL4 antibodies are used in the immunodetection of the protein ST3 beta-galactoside alpha-2,3-sialyltransferase 4. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 38 kDa. Its subcellular localization is in the Golgi and is secreted. Up to 7 different isoforms have been reported for this protein. It is reported to be highly expressed in adult placenta, heart and kidney. A member of the Glycosyltransferase 29 protein family, ST3GAL4 is known to be involved with protein glycosylation. Post-translational modifications have been described, including protein cleavage and glycosylation. Synonyms for this target antigen include NANTA3, SAT3, SIAT4, SIAT4C, ST-4, ST3GalA.2, ST3GalIV, and CGS23. ST3GAL4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of ST3GAL4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
