Scientific Data

Western Blot Detection of Human IRAK3 antibody by Western Blot. View Larger

Detection of Human IRAK3 by Western Blot. Western blot shows lysates of EOL-1 human acute myeloid (eosinophilic) leukemia cell line and THP-1 human acute monocytic leukemia cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human IRAK3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6264) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for IRAK3 at approximately 68 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IRAK3

IRAK3 (Interleukin-1 receptor-associated kinase 3; also IRAK-M) is a 68‑70 kDa member of the Pelle subfamily, TKL Ser/Thr protein kinase family of proteins. IRAK3 has limited expression, being mainly found in macrophages, eosinophils and respiratory epithelium, including type II alveolar cells. IRAK3 is a negative regulator of TLR signaling. Following TLR activation, it appears to form a complex with MyD88, IRAK1 and IRAK4 on the TLR cytoplasmic domain. This effectively blocks IRAK1/4 phosphorylation and inhibits NF kappa B and MAPK downstream activation. Human IRAK3 is 596 amino acids (aa) in length, contains one death domain (aa 41‑106) and a nonfunctional protein kinase domain (aa 171‑443). There are six Ser phosphorylation sites. There is one splice variant with a deletion of aa 45‑105.
