Anti-DYRK4 antibodies are used in the immunodetection of the protein dual specificity tyrosine phosphorylation regulated kinase 4. In humans, the canonical protein has a reported length of 520 amino acid residues and a mass of 59.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is notably expressed in the testis. A member of the CMGC Ser/Thr protein kinase protein family, DYRK4 is suspected to have a non-essential role in spermiogenesis. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include dual specificity tyrosine-(Y)-phosphorylation regulated kinase 4. DYRK4 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chimpanzee species. Western Blot is the most common application for the DYRK4 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
