Anti-CYFIP related Rac1 interactor A antibodies are used for the immunodetection of the protein encoded by the CYRIA gene. In humans, the canonical protein has a reported length of 323 amino acid residues and a mass of 37.3 kDa. Its subcellular localization is in the membrane. A member of the CYRI protein family, it is believed to negatively regulate RAC1 signaling and RAC1-driven cytoskeletal remodeling (Probable). Other names for this target antigen include family with sequence similarity 49 member A and protein FAM49A. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
