Abstract
Interleukin-1 (IL-1) stimulates the association of the IL-1 receptor-associated protein kinase (IRAK) with the heterodimer of IL-1RI and IL-1RAcP via the adapter protein MyD88. In the receptor complex IRAK becomes heavily phosphorylated and concomitantly activated. Here we show that overexpression of a kinase-inactive mutant of IRAK (K239S) inhibits neither IL-1-stimulated activation of the transcription factor NF-kappa B, nor that of the c-Jun N-terminal kinase nor IL-2 production in murine EL-4 cells, but enhances these effects in a manner comparable to wild type IRAK. This strongly suggests that the intrinsic kinase activity is not required for downstream signaling via IRAK. (C) 1999 Federation of European Biochemical Societies.
