Datasheet

MSDS

Rhesus macaque TIGIT (T-cell immunoreceptor with Ig and ITIM domains) is also known as VSIG9 and VSTM3. The recombinant TIGIT protein dimer (CSP-25298-01) is a cis-homodimer (cis-dimer) and contains a TIGIT extracellular domain (UniProt# A0A5F8AKQ5, amino acids Met22-Pro142) fused with a proprietary dimer motif followed by a His-tag at the C-terminus. This protein is expressed in HEK293T cells. The TIGIT-His dimer protein is bioactive and can bind to PVR and TIGIT-specific antibodies. This TIGIT dimer can be used as an antigen for in vitro assays and antibody screening, targeting more conformational epitopes.

Protein Construct: TIGIT protein dimer contains a TIGIT extracellular domainfused with a proprietary cis-dimer motif followed by a His tag at the C-terminus.

Background and Alternate Names

TIGIT (T-cell immunoreceptor with Ig and ITIM domains) is also known as VSIG9 (V-set and immunoglobulin domain-containing protein 9) and VSTM3 (V-set and transmembrane domain-containing protein 3). TIGIT is a Type I membrane protein containing an immunoglobulin variable (Ig-V) domain, a transmembrane domain and cytoplasmic domain. TIGIT is an immune receptor present on peripheral memory and regulatory CD4+ T cells and natural killer (NK) cells. TIGIT is a pivotal immune checkpoint receptor that fine-tunes T-cell and NK-cell responses. Its dual role in promoting tolerance (via Tregs) and suppressing anti-tumor immunity makes it a compelling therapeutic target. TIGIT binds to CD155 (the poliovirus receptor, PVR) with high affinity and binds to CD112 (PVRL2) with lower affinity. Nectin-4 is also a ligand for TIGIT. While structurally and functionally similar to human TIGIT, Rhesus macaque TIGIT is a species-specific tool essential for translational research in cancer immunotherapy.
