Anti-EXTL3 antibodies are used in the immunodetection of the protein exostosin like glycosyltransferase 3. In humans, the canonical protein has a reported length of 919 amino acid residues and a mass of 104.7 kDa. Its subcellular localization is in the nucleus, ER, Golgi, and cell membrane. It is ubiquitously expressed across many tissue types. A member of the Glycosyltransferase 47 protein family, EXTL3 is known to be involved with protein glycosylation. Post-translational modifications have been described, including glycosylation. The EXTL3 gene has been associated with the disease, Immunoskeletal dysplasia with neurodevelopmental abnormalities. Synonyms for this target antigen include EXTL1L, EXTR1, ISDNA, REGR, RPR, exostosin-like 3, EXT-related 1, and BOTV. EXTL3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EXTL3 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
