Abstract: 
Ligand binding in the Toll-like/interleukin-1 receptor family results in the recruitment of an intracellular signaling complex. IRAK-1, which is centrally involved in this complex, is able to homo-oligomerize and to bind to Tollip and the adapters MyD88 and IRAK-4. The interactions of IRAK-1 with MyD88 or Tollip are mediated by the N-terminal part of IRAK-1, containing the death domain with the highly conserved threonine at position 66 (T66). Mutation of this amino acid into alanine or aspartic acid stabilized binding to MyD88, Tollip, and IRAK-4, allowing the definitive experimental proof, that all these interactions are mediated by the death domain of IRAK-1. Homo-oligomerization of IRAK-1, which is mediated by the death domain too, is not affected by mutation of T66. Finally, mutation of IRAK-1 at T66 not only allowed stable binding to the signaling adapters, but also enhanced its signaling capacity. (c) 2007 Elsevier Inc. All rights reserved.
