Anti-RABGGTA antibodies are used in the immunodetection of the protein Rab geranylgeranyltransferase subunit alpha. In humans, the canonical protein has a reported length of 567 amino acid residues and a mass of 65.1 kDa. It is notably widely expressed in many tissue types. A member of the Protein prenyltransferase subunit alpha protein family, RABGGTA is known to catalyze the transfer of a geranylgeranyl moiety from geranylgeranyl diphosphate to both cysteines of Rab proteins with the C-terminal sequence -XXCC, -XCXC and -CCXX, such as RAB1A, RAB3A, RAB5A and RAB7A. Synonyms for this target antigen include geranylgeranyl transferase type-2 subunit alpha, Rab GG transferase alpha, Rab GGTase alpha, Rab geranylgeranyltransferase alpha subunit, and PTAR3. RABGGTA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some RABGGTA antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
