Anti-MGCRACGAP antibodies enable researchers to detect and measure the MGCRACGAP antigen in biological samples. This target is a reported synonym of the RACGAP1 gene, which encodes Rac GTPase activating protein 1. This protein is known to function in erythrocyte differentiation and cell division, among other biological roles. The human version of MGCRACGAP has a canonical amino acid length of 632 residues and a protein mass of 71 kilodaltons. It is reported to be localized in the cell membrane, nucleus, cytoplasmic vesicles, and cytoplasm of cells and notably expressed in many tissues, such as the appendix and duodenum. Other names for this target antigen include CDAN3B, CYK4, and HsCYK-4. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for MGCRACGAP antibodies.
