intracellular chain of KIR3DL1
Encodes the intracellular signaling chain of the KIR3DL1 immune receptor. Inhibits immune cell activation via the ITIM (immunoreceptor tyrosine-based inhibition motif) motif.
Usage and Biology
In immune Natural Killer cells, Killer cell immunoglobulin-like receptors (KIRs) inhibit cell mediated cytotoxicity upon ligand binding. In their intracellular domains, these receptors possess immune tyrosine-based inhibitory (ITIM) motifs that when phosphorylated recruit phosphotases that decrease the activation molecules involved in immune cell signaling.
Function
This part was shown to inhibit the activation of killer cells by the UCSF 2010 team. We used this part in our ANDN gate to increase the precision of killing toward cancer cells. The figure below shows that this part performs its inhibitory function as expected. On the X-axis are different types of target cells, which represent normal and cancer cells expressing different combinations of surface antigents in our experiment. The Y-axis shows the activation levels of killer cells engineered to express synthetic receptors, one of which bears this part as its intracellular domain. The data show that in the presence of antigen B, which is recognized by the synthetic receptor bearing this part, killer cell activation is inhibited (red and striped bars) regardless of the presence of activating antigen A. For more information please see our wiki.
