DAP12 and FcRγ chain are the ITAM-bearing proteins in myeloid cells, while TCRζ chain, and CD3 δ, ε, γ subunits are the predominant ITAM-containing receptors in T cells [ 56 , 57 ].
Witryna1 cze 1997 · Abstract. Cells that are activated following ligation of receptors bearing immunoreceptor tyrosine-based activation motifs (ITAMs) can be negatively … The motif contains a tyrosine separated from a leucine or isoleucine by any two other amino acids, giving the signature YxxL/I. Two of these signatures are typically separated by between 6 and 8 amino acids in the cytoplasmic tail of the molecule (YxxL/Ix(6-8)YxxL/I). However, it is worth noting that in various … Zobacz więcej An immunoreceptor tyrosine-based activation motif (ITAM) is a conserved sequence of four amino acids that is repeated twice in the cytoplasmic tails of non-catalytic tyrosine-phosphorylated receptors, … Zobacz więcej ITAMs are important for signal transduction, mainly in immune cells. They are found in the cytoplasmic tails of non-catalytic tyrosine- Zobacz więcej Examples shown below list both proteins that contain the ITAM themselves and proteins that use ITAM-based signalling with the help of associated proteins which contain the motif.
