Anti-AD031 antibodies enable researchers to detect and measure the AD031 antigen in biological samples. This target is a reported synonym of the ARHGAP42 gene, which encodes Rho GTPase activating protein 42. This protein is known to function in GTPase activation and signal transduction pathways, among other biological roles. The human version of AD031 has a canonical amino acid length of 874 residues and a protein mass of 98.6 kilodaltons.
