These DBY ELISA kits are immunodetection tools for measuring the levels of DBY in biological samples. DBY is an alias of the human DDX3Y gene, which encodes the protein, DEAD-box helicase 3 Y-linked. Notably, DBY is known to play a role in cell differentiation, among other functions. The DDX3Y protein is 660 amino acid residues in length and 73.2 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is found to be widely expressed at the mRNA level, with highest levels in testis. Other names for this target antigen include ATP-dependent RNA helicase DDX3Y.
