Anti-FNBP2 antibodies enable researchers to detect and measure the FNBP2 antigen in biological samples. This target is a reported synonym of the SRGAP2 gene, which encodes SLIT-ROBO Rho GTPase activating protein 2. This protein is known to function in the regulation of cell migration, among other biological roles. The human version of FNBP2 has a canonical amino acid length of 1071 residues and a protein mass of 120.9 kilodaltons. It is reported to be localized in the cell membrane, nucleus, cytoplasmic vesicles, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include ARHGAP34 and SRGAP2A.
