The DEAD (Asp-Glu-Ala-Asp) box polypeptide 19B ELISA kits listed below are analytical tools for measuring concentrations of DEAD (Asp-Glu-Ala-Asp) box polypeptide 19B in various samples. DEAD (Asp-Glu-Ala-Asp) box polypeptide 19B is an alternative name for the human DDX19B gene, which encodes the protein, DEAD-box helicase 19B. The target protein is an ATP-dependent RNA helicase involved in mRNA export from the nucleus. Structurally, the DDX19B protein is 479 amino acid residues in length and 53.9 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include DBP5, DBP5, and DDX19.
