Anti-Fem-1 Homolog A antibodies are used for the immunodetection of the protein encoded by the FEM1A gene. 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, it is known to be involved with protein ubiquitination. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include FEM1-alpha, prostaglandin E receptor 4-associated protein, and protein fem-1 homolog A. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species. Some Fem-1 Homolog A 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.
