Anti-FAXDC2 antibodies are used in the immunodetection of the protein fatty acid hydroxylase domain containing 2. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 39 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the Sterol desaturase protein family, FAXDC2 is reported to promote megakaryocyte differentiation by enhancing ERK phosphorylation and up-regulating RUNX1 expression. Synonyms for this target antigen include C5orf4 and fatty acid hydroxylase domain-containing protein 2. FAXDC2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some FAXDC2 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. Western Blot and Immunofluorescence are also common applications.
