Scientific Data

Western Blot Detection of Human IRAK2 antibody by Western Blot. View Larger

Detection of Human IRAK2 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, Raji human Burkitt's lymphoma cell line, K562 human chronic myelogenous leukemia cell line, and HeLa human cervical epithelial carcinoma cell line. PVDF Membrane was probed with 0.5 µg/mL of Human IRAK2 Monoclonal Antibody (Catalog # MAB6690) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IRAK2 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IRAK2

IRAK2 is an approximately 75 kDa, 625 amino acid (aa) member of the IL-1 receptor-associated kinase (IRAK) family. The four IRAKs are ser/thr kinases that regulate signaling from Toll-like and IL-1 receptors. IRAKs contain N-terminal death domains and central kinase domains, but activity of the IRAK2 kinase domain is unknown. IRAK1 provides initial, and IRAK2 sustained, NFkB activation and proinflammatory cytokine production in macrophages, acting downstream of IRAK4. In the region used as an immunogen, human IRAK2 shares 69% and 70% amino acid identity with mouse and rat IRAK2, respectively.
