Anti-Pixb antibodies are protein reagents that detect specific antigens. The Pixb antigen is another term for the human protein Rho guanine nucleotide exchange factor 7, encoded by the ARHGEF7 gene. The protein is known to act as a RAC1 guanine nucleotide exchange factor (GEF) and can induce membrane ruffling. Canonically, it has an amino acid length of 803 residues and a mass of 90 kilodaltons. Its subcellular localization is in the cell junctions and cytoplasm and it is widely expressed in many tissue types. Other alias names for Pixb include BETA-PIX, BETA-PIX, and COOL-1. Some Pixb antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
