蛋白结构(Molecular Characterization)

KIR2DL4 Structure

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 50.5 kDa. The protein migrates as 55-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

电泳(SDS-PAGE)

KIR2DL4 SDS-PAGE

Human KIR2DL4, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.

 

背景(Background)

Killer cell immunoglobulin-like receptor 2DL4(KIR2DL4), which belongs to the immunoglobulin superfamily, is an inhibitory receptor of NK cells. Soluble HLA-G binds to KIR2DL4 in endosomes and activates the pathway of DNA-PKcs (DNA-dependent protein kinase, catalytic subunit)-AKT-NF-κB signals. The stimulation of the ITIM of KIR2DL4 protein brings about the recruitment and activation of non-receptor protein phosphatases Src homology 2 domain-containing tyrosine phosphatase (SHP)-1 and SHP-2, and the following inhibition of CD16/FcγRIIIa signaling pathway in human NK cells.
