Anti-GIGYF2 antibodies are used in the immunodetection of the protein GRB10 interacting GYF protein 2. In humans, the canonical protein has a reported length of 1299 amino acid residues and a mass of 150.1 kDa. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the GIGYF protein family, GIGYF2 is reported to be a key component of the 4EHP-GYF2 complex, a multiprotein complex that acts as a repressor of translation initiation. The GIGYF2 gene has been associated with the disease, Parkinson disease. Synonyms for this target antigen include PARK11, PERQ2, PERQ3, TNRC15, PERQ amino acid rich, with GYF domain 3, and GYF2. GIGYF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GIGYF2 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
