Anti-YBX1 antibodies are used in the immunodetection of the protein Y-box binding protein 1. In humans, the canonical protein has a reported length of 324 amino acid residues and a mass of 35.9 kDa. Its subcellular localization is in the nucleus, cytoplasm, and is secreted. It is notably widely expressed in many tissue types. A member of the YBX1 protein family, YBX1 is known to be involved with epidermis development and in utero embryonic development. Post-translational modifications have been described, including ubiquitination, protein cleavage and phosphorylation. Synonyms for this target antigen include BP-8 and CBF-A. YBX1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 150 citations in the literature describe the use of YBX1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
