TIGIT Proteins, Antibodies, cDNA Clones Research Reagents

TIGIT (T Cell Immunoreceptor With Ig And ITIM Domains) is a protein coding gene located on human chromosome 3q13.31. TIGIT is also known as VSIG9, VSTM3 and WUCAM. The human TIGIT gene encodes a 26319 Da protein containing 244 amino acids. The TIGIT protein is biasedly expressed in lymph node, spleen and other tissues. Among its related pathways are Hematopoietic Stem Cells and Lineage-specific Markers and Cell adhesion molecules (CAMs). TIGIT is related to signaling receptor binding. CADM2 is an important paralog of TIGIT gene.

        TIGIT Background

        TIGIT, also known as V-set and transmembrane domain-containing protein 3 (VSTM3) or V-set and immunoglobulin domain-containing protein 9 (VSIG9) is a new surface protein containing an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM). TIGIT is expressed on regulatory, memory, activated T cells and NK cells. It binds PVR with high affinity, and PVRL2 with lower affinity, but not PVRL3. Knockdown of TIGIT with siRNA in human memory T cells did not affect T cell responses, however, TIGIT inhibits NK cytotoxicity directly through its ITIM. TIGIT suppresses T cell activation by promoting the generation of mature immunoregulatory dendritic cells. The binding of PVR to TIGIT on human dendritic cells enhanced the production of IL-1 and diminished the production of IL-12p4. Also, TIGIT counter inhibits the NK-mediated killing of tumor cells and protects normal cells from NK-mediated cytotoxicity thus providing an "alternative self" mechanism for MHC class I inhibition.
