Listed are ELISA Kits for the detection of RH-II/GuB, an alias name of DExD-box helicase 50. The human protein, encoded by the gene DDX50, is 737 amino acid residues long and has a mass of 82,565 daltons. It is an enzyme of the RNA helicase class and is a member of the DEAD box helicase family, DDX21/DDX50 subfamily. This protein is reported to have a nuclear cellular localization. This target may also be known as: ATP-dependent RNA helicase DDX50, DEAD (Asp-Glu-Ala-Asp) box polypeptide 50, DEAD box protein 50, DEAD-box helicase 50, gu-beta, malignant cell derived RNA helicase, and nucleolar protein GU2.
