Anti-RAB33B antibodies are used in the immunodetection of the protein RAB33B, member RAS oncogene family. In humans, the canonical protein has a reported length of 229 amino acid residues and a mass of 25.7 kDa. Its subcellular localization is in the Golgi. A member of the Rab protein family, RAB33B is reported to be involved in protein transport. The RAB33B gene has been associated with the disease, Smith-McCort dysplasia. Synonyms for this target antigen include ras-related protein Rab-33B. RAB33B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RAB33B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
