T cell immunoglobulin and ITIM domain (TIGIT), also called WUCAM, Vstm3 and VSIG9, is a 244-amino acid transmembrane glycoprotein that expressed by lymphocytes, particularly in effector and regulatory CD4+ T cells, follicular helper CD4+ T cells, effective CD8+ T cells and NK cells. TIGIT is a member of the CD28 family and functions as a co-inhibitory receptor. TIGIT consists of one extracellular immunoglobulin variable region (IgV), a transmembrane domain and a short intracellular domain with one immunoreceptor tyrosine-based inhibitory motif (ITIM) and one immunoglobulin tyrosine tail (ITT)-like motif. TIGIT binds to CD155 (PVR, Necl5 or Tage4) with a high-affinity and also to CD112 (PVRL2 or nectin 2) and CD113 (PVRL3) with lower affinity. TIGIT potently inhibits innate and adaptive immunity through multiple mechanisms and is crucial for balancing T cell activation and for protection from autoimmunity.
