Anti-ARHGEF39 antibodies are used in the immunodetection of the protein Rho guanine nucleotide exchange factor 39. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 38.3 kDa. Its subcellular localization is in the cell membrane. Up to 4 different isoforms have been reported for this protein. It is reported to be highly expressed in hepatocellular carcinoma (HCC) compared with their non-cancerous counterparts. ARHGEF39 is reported to promote cell proliferation. Synonyms for this target antigen include Rho guanine nucleotide exchange factor (GEF) 39 and vav-like protein C9orf100. ARHGEF39 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the ARHGEF39 antibodies listed below. In addition, Immunohistochemistry is also a common application.
