Further Information

Abbreviation:
TIGIT
Accession:
Q495A1
Activity:
Measured by its ability to bind with human CD155-Fc in a functional ELISA. Measured by its ability to bind with mouse PVR-Fch in a functional ELISA.
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-10 and diminished the production of IL-12p40. In addition; 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.
