Human TIGIT Protein, hFc Tag, Avi Tag

Product Information
Catalog Number KMP2794
Product Name Human TIGIT Protein, hFc Tag, Avi Tag
Product Description The Human TIGIT Protein(KMP2794) is produced in HEK293 Cells. The target gene encoding the human TIGIT (NP_776160.2) (Met1-Pro141) is expressed with a c-terminal Avi tagged Fc region of human IgG1 at the C-terminus (Fc-Avi). The expressed protein is biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed.

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.
Storage Aliquot and store at -20℃ to -80℃. Avoid repeated freezing and thawing cycles.
