Anti-NOMA-GAP antibodies are protein reagents that detect specific antigens. The NOMA-GAP antigen is another term for the human protein Rho GTPase activating protein 33, encoded by the ARHGAP33 gene. The protein is suspected to be involved in several stages of intracellular trafficking. Canonically, it has an amino acid length of 1287 residues and a mass of 137.2 kilodaltons. It is widely expressed in many tissue types. The NOMA-GAP protein is a member of the PX domain-containing GAP protein family.
