Anti-F-box protein 43 antibodies are used for the immunodetection of the protein encoded by the FBXO43 gene. In humans, the canonical protein has a reported length of 708 amino acid residues and a mass of 78.4 kDa. It is reported to be expressed in the testis. It is known to be required to establish and maintain the arrest of oocytes at the second meiotic metaphase until fertilization. Post-translational modifications have been described, including ubiquitination and phosphorylation. The gene encoding this protein is implicated in Oocyte maturation defect. Other names for this target antigen include early mitotic inhibitor 2, endogenous meiotic inhibitor 2, and F-box only protein 43. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of F-box protein 43 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
