Scientific Data

Western Blot Detection of Human DRAK1 antibody by Western Blot. View Larger

Detection of Human DRAK1 by Western Blot. Western blot shows lysates of JEG-3 human epithelial choriocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human DRAK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4985) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). 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 1.

Background: DRAK1

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 is 95% aa identical to canine DRAK1, and 65% aa identical to human DRAK2.
