Anti-ARHGEF9 antibodies are used in the immunodetection of the protein Cdc42 guanine nucleotide exchange factor 9. In humans, the canonical protein has a reported length of 516 amino acid residues and a mass of 61 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the brain. ARHGEF9 is known to act as guanine nucleotide exchange factor (GEF) for CDC42. The ARHGEF9 gene has been associated with the disease, Developmental and epileptic encephalopathy. Synonyms for this target antigen include DEE8, EIEE8, HPEM-2, PEM-2, PEM2, and COLLYBISTIN. ARHGEF9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ARHGEF9 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
