Anti-DEAD/H box helicase 11 antibodies are used for the immunodetection of the protein encoded by the DDX11 gene. In humans, the canonical protein has a reported length of 970 amino acid residues and a mass of 108.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 5 different isoforms for this protein. It is reported to be expressed in melanoma cells. A member of the DEAD box helicase protein family, it is known to be involved with DNA damage pathways and DNA repair. The gene encoding this protein is implicated in Warsaw breakage syndrome. Other names for this target antigen include CHLR1, KRG2, WABS, ATP-dependent DNA helicase DDX11, CHL1-like helicase homolog, and CHL1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
