CD28H (CD28 homolog), also known as TMIGD2 (transmembrane and immunoglobulin domain-containing protein 2) and IGPR1 (immunoglobulin and proline-rich receptor 1), is a single-pass type I transmembrane glycoprotein. CD28H contains 1 Ig (immunoglobulin)-like domain in the extracellular region and 1 cytoplasmic proline-rich domain. CD28H is widely expressed, mainly by epithelial and endothelial cells. It is also expressed in lymphoid organs, with highest levels in thymus, spleen, peripheral blood lymphocytes and liver. In the thymus, it is expressed in CD4 and CD8 single- and double-positive cells, but not in immature CD4 and CD8 double-negative cells. In peripheral blood mononuclear cells, CD28H is highly expressed on natural killer (NK) cells and CD3+ T-cells but not on B-cells. CD28H may form homophilic interactions that could regulate cell-cell interaction, cell migration, and angiogenesis. The B7 family member B7-H7 (B7 homolog 7), also know n as HHLA2 (human endogenous retrovirus-H long terminal repeat-associating protein 2), was identified as a specific ligand for CD28H. Through interaction with B7-H7, CD28H may co-stimulate T-cells in the context of TCR-mediated activation. The B7-H7/CD28H interaction selectively co-stimulates human T-cell growth and cytokine production via an AKT-dependent signalling cascade.
Gene Symbol: CD28H; TMIGD2; IGPR1; IGPR-1;UNQ3059/PRO9879
NCBI Gene ID: 126259
Uniprot Entry: Q96BF3
Construct Details: Full length human CD28H/TMIGD2 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)

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.
