  • Function

    Binds with high affinity to the poliovirus receptor (PVR) which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T cell activation by promoting the generation of mature immunoregulatory dendritic cells.
  • Tissue specificity

    Expressed at low levels on peripheral memory and regulatory CD4+ T cells and NK cells and is up-regulated following activation of these cells (at protein level).
  • Sequence similarities

    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Domain

    Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
  • Cellular localization

    Cell membrane.
  • Information by UniProt

Images

  • Human TIGIT, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
  • FACS assay shows that recombinant Human TIGIT Protein, Fc Tag can bind to 293T cell overexpressing human CD155. The concentration of TIGIT used is 0.1 µg/ml.
  • Immobilized Human CD155, mouse IgG2a Fc tag, low endotoxin at 5 µg/mL (100 µL/well) can bind Human TIGIT, Fc Tag with a linear range of 0.6-5 ng/mL.
  • ab224646 analyzed by SDS-PAGE under reducing conditions and stained overnight with Coomassie Blue.

    The protein migrates as 40-55 kDa under reducing conditions due to glycosylation.
