Anti-DEAD-box helicase 3, X-linked antibodies are used in antigen-specific immunodetection in biological samples. The target DEAD-box helicase 3, X-linked is a known alias name of the protein DEAD-box helicase 3 X-linked, encoded by the DDX3X gene in humans. This 662-amino acid residue protein is known to be involved in cell differentiation and viral immune response, among other biological processes. It is localized to the cell membrane, nucleus, and cytoplasm of the cell and features cleaved and phosphorylated post-translational modifications. In terms of tissue expression, it is widely expressed across many tissue types.
