T cell immunoreceptor with lg and ITIM domains (TIGIT) is a recently identified immune checkpoint protein expressed on Natural Killer cells (NK) and T cells. TIGIT is an inhibitory receptor which controls the immune activity by competing with activating receptor CD226 (also called DNAM-1) for ligand binding. This on and off switch of TIGIT and DNAM-1 corresponds with CTLA4 and CD28, making it a potential target for anti-tumor therapy.
CD112 (Nectin-2 or PVRL2) and CD155 (PVR) are co-ligands of DNAM-1 and TIGIT, while CD113 (Nectin-3 or PVRL3) only binds with TIGIT. The affinity between various ligands and receptors can differ. The binding between CD155 and TIGIT is stronger than that between CD113 or CD112 and TIGIT.
ACROBiosystems brings an extensive collection of recombinant proteins from TIGIT signaling axis. Besides the widely used Fc and His-labeled proteins, the company also brings multiple pre-biotinylated proteins such as Biotinylated Human CD155/PVR Protein, Fc Tag, Avi Tag (Avitag™) (Cat. No. CD5-H82F6); Biotinylated Human TIGIT, Avi Tag (Avitag™) (Cat. No.TIT-H82E5); Biotinylated Human Nectin-2/CD112 Protein, Fc Tag, Avi Tag (Avitag™) (Cat. No. CD2-H82F8).
