Anti-p120RASGAP antibodies are protein reagents that detect specific antigens. The p120RASGAP antigen is another term for the human protein RAS p21 protein activator 1, encoded by the RASA1 gene. The protein is a reported inhibitory regulator of the Ras-cyclic AMP pathway. Canonically, it has an amino acid length of 1047 residues and a mass of 116.4 kilodaltons. Its subcellular localization is in the cytoplasm and it is expressed in the placenta, fallopian tube, and bronchus. Other alias names for p120RASGAP include CM-AVM, CMAVM, and CMAVM1. These p120RASGAP antibodies are widely used in Western Blot experiments, among other applications.
