Detection of Human DRAK1 by Western Blot. Western blot shows lysates of MOLT‑4 human acute lymphoblastic leukemia cell line and A431 human epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human DRAK1 Monoclonal Antibody (Catalog # MAB4985) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for DRAK1 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

DRAK1 (DAP kinase-related apoptosis-inducing protein kinase 1; also STK17A) is a 55 kDa member of the DAP kinase subfamily, CAMK Ser/Thr protein kinase family of enzymes. It is expressed in osteoclasts, resides in the nucleus, and initiates apoptosis. Human DRAK1 is 414 amino acids (aa) in length. It contains an N-terminal polyPro segment (aa 33-37) followed by a Ser/Thr kinase domain (aa 64-321) with a catalytic loop (aa 184-193). Apoptosis apparently requires an intact kinase domain. No rodent DRAK1 has been reported. Over aa 115-313, human DRAK1 shares 95% aa identity with canine DRAK1, and 65% aa identity with human DRAK2.
