Recombinant Cynomolgus TIGIT/VSIG9/VSTM3 (C-6His)
Recombinant Cynomolgus monkey TIGIT is produced by our Mammalian expression system and the target gene encoding Met89-Pro209 is expressed with a 6His tag at the C-terminus. Bon Opus Cat. #CP02
BackgroundT cell immunoreceptor with Ig and ITIM domains (TIGIT), also called VSIG9 and Vstm3, is a member of the CD28 family within the Ig superfamily of proteins. TIGIT contains an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM), and is expressed on regulatory, memory, activated T cells and NK cells. TIGIT binds to CD155(PVR) that appear on dendritic cells (DC), macrophages and endothelium with high affinity, and CD112(PVRL2) with lower affinity, but not CD113 (PVRL3). TIGIT-Fc fusion protein could interact with PVR on DC and enhance the secretion of IL-10, but inhibit the macrophage activation. Mice lacking TIGIT show increased T cell responses and susceptibility to autoimmune challenges, while knockdown of TIGIT with siRNA in human memory T cells did not affect T cell responses.
FormulationLyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
