Anti-WRP antibodies enable researchers to detect and measure the WRP antigen in biological samples. This target is a reported synonym of the SRGAP3 gene, which encodes SLIT-ROBO Rho GTPase activating protein 3. This protein is known to function in the regulation of cell migration and GPCR signaling pathways, among other biological roles. The human version of WRP has a canonical amino acid length of 1099 residues and a protein mass of 124.5 kilodaltons, although 3 isoforms have been identified. It is reported to be notably expressed in many tissues, such as the colon and rectum. Other names for this target antigen include ARHGAP14, MEGAP, and SRGAP2.
