NKG2C-CD94 Heterodimer Protein, Human (HEK293, His-Avi)

The NKG2C/CD159c protein is an immune-activating receptor that plays a critical role in self-non-self discrimination. It cooperates with KLRD1 to recognize non-classical MHC class Ib HLA-E loaded with HLA-G peptides, affecting adaptive NK cell function and maternal-fetal tolerance. NKG2C-CD94 Heterodimer Protein, Human (HEK293, His-Avi-Flag) is a recombinant protein dimer complex containing human-derived NKG2C-CD94 Heterodimer protein, expressed by HEK293 , with N-His, N-Avi labeled tag. NKG2C-CD94 Heterodimer Protein, Human (HEK293, His-Avi-Flag), has molecular weight of 30-50 kDa.

NKG2C/CD159c Protein, an immune activating receptor, plays a pivotal role in self-nonself discrimination. Teaming up with KLRD1 on cytotoxic lymphocyte subsets, it recognizes non-classical major histocompatibility (MHC) class Ib HLA-E loaded with signal sequence-derived peptides from non-classical MHC class Ib HLA-G molecules. This interaction likely contributes to the generation and effector functions of adaptive natural killer (NK) cells and is implicated in maternal-fetal tolerance during pregnancy. NKG2C/CD159c also regulates the effector functions of terminally differentiated cytotoxic lymphocyte subsets, particularly in the adaptive NK cell response to viral infection. Upon binding to HLA-E-peptide complexes, NKG2C/CD159c transmits intracellular signals through the adapter protein TYROBP/DAP12, initiating the phosphorylation of proximal signaling molecules and subsequent cell activation. Forming a heterodimer with KLRD1 through disulfide linkage, the KLRD1-KLRC2 receptor complex, in association with TYROBP homodimers, is crucial for its cell surface expression. Additionally, this receptor complex can bind with low affinity to HLA-E loaded with self-peptides derived from the signal sequence of classical MHC class Ia. The multifaceted interactions and functions of NKG2C/CD159c underscore its essential role in immune responses and self-tolerance mechanisms.

Approximately 30-50 kDa,based on SDS-PAGE under reducing conditions,due to the glycosylation.

≥ 95%, as determined by Bis-Tris PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
