Description

B7H3 (B7 homolog 3), also known as CD276, is a single pass type I transmembrane glycoprotein that belongs to the B7 family of the Ig superfamily. Like other B7 family members, B7-H3 contains one Ig V-like and one Ig C-like domain in the extracellular region. Among the family members, they share about 20-25% amino acid identity. B7-H3 serves as an accessory modulator of T-cell response. It has been reported that B7-H3 can provide both a stimulatory and inhibitory signal to T cells. As a negative regulator, it preferentially affects Th1 responses. B7-H3 may also play an important role in muscle-immune interactions. A longer form of B7-H3 has been identified in human but not in mouse. It is termed 4IgB7H3 or B7H3b with two additional Iglike domains (one V-type and one C-type). B7-H3b appears to be the dominantly expressed form in human and is found on human dendritic cells, activated T, B and NK cells. Human B7H3b binding to an undefined receptor may inhibit NK cell killing and cytokine release. It is also involved in late stage osteoblast differentiation. B7-H3 is detected in a variety of cancer types and its expression in some cancers correlates with poor outcome of cancer patients.

Product Details

Gene Symbol: B7-H3; CD276; B7H3; B7RP-2; 4Ig-B7-H3; PSEC0249; UNQ309/PRO352

NCBI Gene ID: 80381

Uniprot Entry: Q5ZPR3

Construct Details: Full length human B7-H3/CD276 gene (encoding UniProt accession #Q5ZPR3 isoform 2, also known as 2Ig-B7-H3) 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: 951(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.
