Anti-GIGYF1 antibodies are used in the immunodetection of the protein GRB10 interacting GYF protein 1. In humans, the canonical protein has a reported length of 1035 amino acid residues and a mass of 114.6 kDa. It is notably widely expressed in many tissue types. A member of the GIGYF protein family, GIGYF1 is believed to act cooperatively with GRB10 to regulate tyrosine kinase receptor signaling. Synonyms for this target antigen include postmeiotic segregation increased 2-like 12, and PERQ amino acid-rich with GYF domain-containing protein 1. GIGYF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some GIGYF1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
