Anti-CSGALNACT1 antibodies are used in the immunodetection of the protein chondroitin sulfate N-acetylgalactosaminyltransferase 1. In humans, the canonical protein has a reported length of 532 amino acid residues and a mass of 61.3 kDa. Its subcellular localization is in the Golgi. Up to 3 different isoforms have been reported for this protein. It is found to be widely expressed, with the highest levels in the placenta, thyroid, bladder, prostate and adrenal gland. A member of the Chondroitin N-acetylgalactosaminyltransferase protein family, CSGALNACT1 is known to be involved with cartilage development and extracellular matrix organization. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include chondroitin beta-1,4-N-acetylgalactosaminyltransferase 1, chondroitin beta1,4 N-acetylgalactosaminyltransferase, glucuronylgalactosylproteoglycan 4-beta-N- acetylgalactosaminyltransferase, and beta4GalNAcT-1. CSGALNACT1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. ELISA, Western Blot, and Immunohistochemistry are common applications for CSGALNACT1 antibodies.
