Detection of Human DAPK3/ZIPK by Western Blot. Western blot shows lysates of A431 human epithelial carcinoma cell line, HeLa human cervical epithelial carcinoma cell line, and HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human DAPK3/ZIPK Monoclonal Antibody (Catalog # MAB5290) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for DAPK3/ZIPK at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

DAPK3 (Death-associated protein kinase 3; also ZIP kinase and DLK) is a 52 kDa member of the CAMK Ser/Thr kinase family, protein kinase superfamily of enzymes. In general, mouse DAPK3 is nuclear while human DAPK3 is cytosolic. DAPK3 is found in smooth muscle where it phosphorylates the regulatory light chain of myosin and stabilizes thick filament formation. Human DAPK3 is 454 amino acids (aa) in length. It contains one protein kinase domain (aa 134-275) and a C‑terminal Leu-zipper motif (aa 427-441) that mediates homo- and hetero-dimerization. There is one 35 kDa alternate splice form that shows a 10 aa substitution for aa 313-454. This form has both a nuclear and cytosolic localization. Over aa 347‑454, human DAPK3 is 65% aa identical to mouse DAPK3.
