Human TIM-3 Full-length Gene in Lentivector, Endotoxin-free DNA
TIM3 (T cell immunoglobulin and mucin domain3), also known as HAVCR2, is a single-pass type I transmembrane glycoprotein of the TIM family of Ig superfamily. Like other family members, TIM-3 contains one Iglike Vtype domain and a Ser/Thrrich mucin stalk domain in the extracellular region. An alternatively spliced isoform is truncated within the mucinlike stalk. TIM-3 is selectively expressed on Th1 (T-helper type 1) cells but not on Th2 cells. Th1 cells produce cytokines (IFN-γ, interleukin-2, TNF-α and lymphotoxin) associated with cell-mediated immune responses against intracellular pathogens, delayed-type hypersensitivity, and induction of organ-specific autoimmunity. TIM3 is upregulated on activated myeloid cells and T cells. TIM-3 regulates macrophage activation and inhibits Th1-mediated auto- and allo-immune responses to promote immunological tolerance. It may be also involved in T-cell homing. Galectin9 has been identified as a ligand for TIM-3. The binding of Galectin-9 to TM-3 enhances immune tolerance and inhibits antitumor immunity. It can alternatively trigger immune stimulatory effects, such as the co-activation of NK cell cytotoxicity. TIM3 dampens inflammation by enabling the phagocytosis of apoptotic cells and the crosspresentation of apoptotic cell antigens. Dysregulation of the Galectin-9/TIM-3 pathway is implicated in many chronic autoimmune conditions in human, such as multiple sclerosis and systemic lupus erythematosus.
Gene Symbol: TIM-3; TIM3; TIMD3; TIMD-3; KIM-3; HAVCR2; HAVCR-2
NCBI Gene ID: 84868
Uniprot Entry: Q8TDQ0
Construct Details: Full length human TIM-3 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter, which can be used for both transient and stable expression in mammalian cells. It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles.
Vector Type: pLTC (lentiviral expression vector containing a heterologous CMV promoter, see the vector map above)
Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)
Gene Insert Size: 906 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:
(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;
(b) reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’
Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification. High fidelity PCR systems should always be used.
