Description

NKp30 (activating natural killer receptor NKp30), also known as CD337 and Natural Cytotoxicity Triggering Receptor 3 (NCR3), is a member of the natural cytotoxicity receptor (NCR) family. The NCR family are comprised of three type I transmembrane receptors that are expressed almost exclusively by NK cells, includes NKp30, NKp44, and NKp46. NKp30 is a 30 kDa glycosylated protein having one extracellular immunoglobulin-like domain and a hydrophobic TM domain. Six isoforms of NKp30 can be produced by alternative splicing, termed NKp30a-f. NKp30 is expressed on all mature resting and activated NK cells. NKp30 plays an important role in triggering NK cell cytolytic activity. It can enhance NK cell cytolysis of tumor cells that are deficient in MHC class I molecules, either independently or in cooperation with NKp44 and/or NKp46. NKp30 has been reported to have a unique role in NK-mediated lysis of immature dendritic cells. NK cells can kill autologous immature dendritic cells via ligation of NKp30. Alternately, NK cells can also promote the maturation of immature dendritic cells through engagement of NKp30. Heparan Sulfate Glycosaminoglycans, B7-H6, HLA-B-associated transcript 3 (BAT3)/Bcl2-associated anthogene 6 (BAG6), and Galectin-3 were identified as ligands for NKp30. Nkp30 can associate with T cell CD3 receptor zeta (TCRζ) and/or FcRγ via its TM domain with a charged arginine residue. NKp30 also has been shown to associate with CD59. NKp30 may serve as a potential target for therapeutics for cancers, autoimmune, disease atopic diseases, and Infectious diseases.

Product Details

Source
Biotinylated recombinant human NKp30/NCR3, amino acid Leu19-Thr138 (Accession# O14931.1), with a linker, a C-terminal human IgG1 (Pro100-Lys330) and an Avi-tag, was expressed in 293E cells. Human NKp30/NCR3-Avi tag was site-specifically biotinylated by enzyme BirA.
Molecular Mass
The 372 amino acid recombinant protein has a predicted molecular mass of approximately 41.53 kD. The DTT-reduced and non-reduced protein migrates at approximately 50–70 kD and 80–125 kD by SDS-PAGE, respectively. The predicted N-terminal amino acid is Leu.
Purity
> 95%, as determined by Coomassie stained SDS-PAGE.
Formulation
0.22 µm filtered protein solution is in PBS, pH 7.2
Endotoxin Level
Less than 0.1 EU per µg cytokine as determined by the LAL method.
Concentration
25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin the vial prior to opening. Stock solutions should be prepared at no less than 50-100 µg/mL in sterile buffer (PBS, HPBS, DPBS, and EBSS) containing carrier protein such as 0.2 - 1% BSA or HSA and stored in working aliquots at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Activity
When recombinant human B7-H6-Fc Chimera (Cat. No. 794006) is immobilized at 1 µg/mL, biotinylated recombinant human NKp30/NCR3 binds in a dose-dependent manner with ED50 of 3 – 18 ng/mL.
