The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesICC/IF: Use at a concentration of 10 µg/ml.
WB: Use at a concentration of 1 - 2 µg/ml. Detects a band of approximately 50 kDa. Can be blocked with IRAK4 peptide (448-460) (ab39782).
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionRequired for the efficient recruitment of IRAK1 to the IL-1 receptor complex following IL-1 engagement, triggering intracellular signaling cascades leading to transcriptional up-regulation and mRNA stabilization. Phosphorylates IRAK1.
Involvement in diseaseDefects in IRAK4 are the cause of recurrent isolated invasive pneumococcal disease type 1 (IPD1) [MIM:610799]. Recurrent invasive pneumococcal disease (IPD) is defined as two episodes of IPD occurring at least 1 month apart, whether caused by the same or different serotypes or strains. Recurrent IPD occurs in at least 2% of patients in most series, making IPD the most important known risk factor for subsequent IPD. Defects in IRAK4 are the cause of IRAK4 deficiency (IRAK4D) [MIM:607676]. IRAK4 deficiency causes extracellular pyogenic bacterial and fungal infections in otherwise healthy children.
Sequence similaritiesBelongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. Pelle subfamily. Contains 1 death domain. Contains 1 protein kinase domain.
