Anti-RHOU antibodies are used in the immunodetection of the protein ras homolog family member U. In humans, the canonical protein has a reported length of 258 amino acid residues and a mass of 28.2 kDa. Its subcellular localization is in the Golgi and cell membrane. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Rho protein family, Rhou is known to act upstream of PAK1 to regulate the actin cytoskeleton, adhesion turnover and increase cell migration. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include 2310026M05Rik, CDC42-like GTPase 1, GTP-binding protein SB128, GTP-binding protein like 1, Ryu GTPase, and rho-related GTP-binding protein RhoU. RHOU gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of Rhou antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
