Anti-DAZ4 antibodies are used in the immunodetection of the protein deleted in azoospermia 4. In humans, the canonical protein has a reported length of 579 amino acid residues and a mass of 64.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to have testis-specific expression. A member of the RRM DAZ protein family, DAZ4 is reported to be a RNA-binding protein that plays an essential role in spermatogenesis. The DAZ4 gene has been associated with the disease, Spermatogenic failure Y-linked. Synonyms for this target antigen include deleted in azoospermia protein 4. Western Blot is the most common application for the DAZ4 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
