KLRG1 belongs to the killer cell lectin-like receptor (KLR) or NKG2 family of the C-type lectin superfamily, which is a group of single pass type II transmembrane proteins preferentially expressed in natural killer (NK) cells.  NK cells are lymphocytes that can mediate lysis of certain tumor cells and virus-infected cells without previous activation. NK cells regulate specific humoral and cell-mediated immunity. The KLR/NKG2 family is characterized by the presence of a C-type lectin domain in the extracellular region at the C-terminus. KLRG1 forms a disulfide-bond linked  homodimer. KLRG1 is expressed specifically on natural killer (NK) cells and T-cells, mainly CD8 T-cell. KLRG1 contains 1 copy of a cytoplasmic motif referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM) involved in modulation of cellular responses. KLRG1 plays an inhibitory role on natural killer (NK) cells and T-cell functions upon binding to their non-MHC ligands. KLRG1 may mediate missing self recognition by binding to a highly conserved site on classical cadherins, enabling it to monitor expression of E-cadherin/CDH1, N-cadherin/CDH2 and R-cadherin/CDH4 on target cells.

Product Details

 

Gene Symbol: KLRG2; CLEC15B

 

NCBI Gene ID: 346689

 

Uniprot Entry: A4D1S0

 

Construct Details: Full length human KLRG2 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without 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. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, 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: 1230 (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.
