Anti-DEAD-box helicase 1 antibodies are used for the immunodetection of the protein encoded by the DDX1 gene. In humans, the canonical protein has a reported length of 740 amino acid residues and a mass of 82.4 kDa. Its subcellular localization is in the nucleus, mitochondria, and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the DEAD box helicase protein family, it is known to act as a ATP-dependent RNA helicase, able to unwind both RNA-RNA and RNA-DNA duplexes. Other names for this target antigen include UKVH5d, ATP-dependent RNA helicase DDX1, DEAD (Asp-Glu-Ala-Asp) box helicase 1, DEAD (Asp-Glu-Ala-Asp) box polypeptide 1, DEAD box polypeptide 1, and DBP-RB. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of DEAD-box helicase 1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
