human ... DDX4(54514)

General description

DDX4 (DEAD [Asp-Glu-Ala-Asp] box polypeptide 4), also known as Vasa, is encoded by the gene mapped to human chromosome 5q11.2. The encoded protein belongs to the DEAD box protein family. DDX4 is characterized by two functional domains containing nine conserved sequence motifs. Domain I (DEADc) contains six of these motifs and domain II (HELICc) contains motifs IV, V, and VI. DDX4 is a cytoplasmic protein and is highly expressed in spermatocytes and mature oocytes.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

Genome-wide association studies identified DEAD-box helicase 4 (DDX4) loci as a genetic risk factor for the susceptibility to the pathogenesis of low-risk neuroblastoma. The encoded protein is an ATP-dependent RNA helicase and is a highly conserved component of the germ plasma. DDX4 acts as a potential marker of the germ cell lineage. DDX4 as an RNA helicase plays a vital role in various cellular processes such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
