IRAK4 Mouse anti-Human, PE, Clone: L29-525, BD

Interleukin 1 (IL-1) is a proinflammatory cytokine that mediates the host inflammatory response. IL-1 exerts its biological effects through its type I receptor (IL-1RI), which is found on most cell types. When IL-1 binds to the IL-1RI, NF-κB (transcription factor) is activated and translocates to the nucleus where it induces gene expression. IL-1-receptor-associated kinase (IRAK) has been reported to co-immunoprecipitate with IL-1RI. The IRAK family is made up of four identified Pelle homologs that regulate the activation of NF-κB and mitogen-activated protein (MAP) kinase pathways. IRAK4 is a unique member of the IRAK family because it is the closest mammalian homolog to Pelle. Also, when overexpressed, its kinase activity allows it to activate both the NF-κB and mitogen-activated protein (MAP) kinase pathways, and block the IL-1-induced activation and modification of IRAK1. IRAK4 is also able to phosphorylate IRAK1, which suggests that IRAK4 affects the early signal transduction of Toll/IL-1 receptors before the involvement of IRAK1. The L29-525 monoclonal antibody recognizes human IRAK4, regardless of phosphorylation status. The specificity of this antibody conjugate for flow cytometric analysis was validated by confirming that RNA-mediated interference (RNAi) of the specific protein reduced the staining of the cells (see figure). Furthermore, the capacity of the RNAi to down-regulate the expression of the relevant protein was confirmed by western blot analysis.
