Anti-DExH-box helicase 9 antibodies are used for the immunodetection of the protein encoded by the DHX9 gene. In humans, the canonical protein has a reported length of 1270 amino acid residues and a mass of 141 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the DEAD box helicase protein family, it is known to be involved with TNF-mediated cellular signaling pathways and DNA replication. Post-translational modifications have been described, including methylation and phosphorylation. Other names for this target antigen include LKP, NDH2, NDHII, RHA, ATP-dependent RNA helicase A, and DDX9. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 70 citations in the literature describe the use of DExH-box helicase 9 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
