Human NCR1/CD335/NKp46/NCTR1 Gene, Full-length cDNA Clone in Lentivector, Endotoxin-free DNA

Description

NCR1, also known as NKp46 and CD335, is a single-pass type I transmembrane glycoprotein that contains two extracellular Immunoglobulin (Ig)-like domains and a short cytoplasmic tail.  CD335 together with NCR2/NKp44/CD336 and NCR3/NKp30/CD337 are activating receptors collectively termed the natural cytotoxicity receptors (NCRs). All these receptors lack significant sequence homology to one another. They are expressed almost exclusively by NK cells and are primarily responsible for triggering NK cell-mediated lytic activities of human tumor cells. CD335 and its co-receptor CD59 together activate cytotoxicity of human NK-cells by the association with ITAM­ bearing signal adapter proteins, including CD3ζ and FcεR1γ, which are able to form disulfide­linked homodimers and heterodimers. Blocking any of these three NCRs individually resulted in partial inhibition of tumor cell lysis, but nearly complete inhibition of lysis was observed if all three receptors were blocked simultaneously. CD335 is also implicated in NK cell-mediated lysis of pathogen-infected cell lines and mononuclear phagocytes infected with an intracellular bacterium. CD335 recognizes virus­infected cells through its capacity to bind to viral hemagglutinins.  CD335 is involved in NK-cell cell death by apoptosis. 

 

 

Gene Symbol: NCR1; LY94; CD335; NKP46; NK-p46; hNKp46; NCTR1

 

NCBI Gene ID: 9437

 

Uniprot Entry: O76036

 

Construct Details: Full length human NCR1/CD335/NKp46 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and a selection marker, 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 or pLTC-IRES-Marker (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: 915 (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’-CCAGGTTTCCGGGCCCTCAC-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.
