Anti-IER3IP1 antibodies are used in the immunodetection of the protein immediate early response 3 interacting protein 1. In humans, the canonical protein has a reported length of 82 amino acid residues and a mass of 9 kDa. Its subcellular localization is in the ER. It is reported to be highly expressed in the heart, skeletal muscle, and kidney. A member of the YOS1 protein family, IER3IP1 is a reported regulator of endoplasmic reticulum secretion that acts as a key determinant of brain size. The IER3IP1 gene has been associated with the disease, Microcephaly, epilepsy, and diabetes syndrome. Synonyms for this target antigen include MEDS, PRO2309, and HSPC039. IER3IP1 gene orthologs have been reported in the mouse, bovine, frog, zebrafish, chimpanzee and chicken species. Some IER3IP1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
