ITAM motif in an apoptosis-receptor

O Lohi et al. Apoptosis. 1998 Oct.

Abstract

Signal transduction by the T-cell and B-cell antigen receptors and receptors for immunoglobulin Fc regions depends highly on the cytoplasmic immunoreceptor tyrosine-based activation motif (ITAM). After binding of the ligand, phosphorylation of the two conserved tyrosines of ITAM creates binding sites for downstream signalling molecules and thus enables the initiation of signalling events. Here, we report that the recently found apoptosis receptor, WSL-1/DR3/APO-3/LARD/TRAMP also contains this motif. This may imply that the apoptosis receptor uses ways similar to immunoreceptors in relaying the induction/suppression of the apoptotic signal.
