Anti-DEAD-box helicase 47 antibodies are used in the immunodetection of the protein encoded by the DDX47 gene. In humans, the canonical protein has a reported length of 455 amino acid residues and a mass of 50.6 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in skin, lung and breast. A member of the DEAD box helicase protein family, it is known to be required for efficient ribosome biogenesis (By similarity). Other names for this target antigen include HQ0256, MSTP162, RRP3, probable ATP-dependent RNA helicase DDX47, DEAD (Asp-Glu-Ala-Asp) box polypeptide 47, and E4-DBP.
