title: Cloning of the Atlantic salmon (Salmo salar) IL-1 receptor associated protein.
abstract: In mammals, the pro-inflammatory cytokine interleukin-1 signals through a receptor complex containing a type I interleukin-1 receptor (IL-1RI) and a receptor associated protein (IL-1RAcP). Previously, we have described a cDNA from Atlantic salmon encoding a molecule with homology to the mammalian IL-RI. This molecule was named IL-1 receptor like protein (IL-1RLP) in the absence of functional data to support its proposed role as the salmon IL-1RI. Here, we describe the cloning and characterisation of a cDNA encoding salmon IL-1RAcP. Like other members of the IL-1R family, the salmon IL-1RAcP encodes three extracellular immunoglobulin-like domains and a cytoplasmic Toll/Interleukin-1 receptor (TIR) domain involved in signalling. Specific binding of salmon IL-1RAcP to IL-1RLP was shown by co-immunoprecipitation studies.
