Anti-FEM1A antibodies are used in the immunodetection of the protein fem-1 homolog A. In humans, the canonical protein has a reported length of 669 amino acid residues and a mass of 73.6 kDa. Its subcellular localization is in the mitochondria and cytoplasm. A member of the Fem-1 protein family, FEM1A is known to be involved with protein ubiquitination. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include FEM1-alpha, prostaglandin E receptor 4-associated protein, and protein fem-1 homolog A. FEM1A gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some FEM1A antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
