NCIt definition : ITAM (Immunoreceptor Tyrosine-based Activation Motif) or ARAM (Ag Recognition Activation
Motif) (Y-X-X-L-(X)6-8-Y-X-X-L), a protein domain involved in STP, binds to SH2 domain,
e.g. in CD247/x chain, FceRI g chain, or DAP12. Phosphorylated immunoreceptor signaling
motifs (ITAMs) exhibit unique abilities to bind and activate Lyn and Syk tyrosine
kinases. Motif may be dually phosphorylated on tyrosine that links antigen receptors
to downstream signaling machinery.;
