Anti-SMIM20 antibodies are used in the immunodetection of the protein small integral membrane protein 20. In humans, the canonical protein has a reported length of 67 amino acid residues and a mass of 7.7 kDa. Its subcellular localization is in the mitochondria and is secreted. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the ovary, specifically in granulosa cells of follicles that have passed the primary stage and in oocytes. Synonyms for this target antigen include phoenixin, and mitochondrial translation regulation assembly intermediate of cytochrome c oxidase protein of 7 kDa. SMIM20 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunocytochemistry is the most common application for the SMIM20 antibodies listed below. Western Blot, Immunofluorescence, and Immunohistochemistry are also common applications.
