Anti-DDX19A antibodies are used in the immunodetection of the protein DEAD-box helicase 19A. In humans, the canonical protein has a reported length of 478 amino acid residues and a mass of 54 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 a the DEAD box helicase protein family, DDX19A is an ATP-dependent RNA helicase involved in mRNA export from the nucleus. Synonyms for this target antigen include DDX19L, ATP-dependent RNA helicase DDX19A, DDX19-like protein, DEAD (Asp-Glu-Ala-As) box polypeptide 19A, DEAD (Asp-Glu-Ala-Asp) box polypeptide 19A, and DDX19-DDX19L.
