Anti-DDX42 antibodies are used in the immunodetection of the protein DEAD-box helicase 42. In humans, the canonical protein has a reported length of 938 amino acid residues and a mass of 103 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in several cell lines. A member of the DEAD box helicase protein family, DDX42 is known to be involved with protein localization and the regulation of apoptosis. Synonyms for this target antigen include RHELP, RNAHP, SF3B8, SF3b125, ATP-dependent RNA helicase DDX42, and DDX42P. DDX42 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the DDX42 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
