分子别名(Synonym)

NCR3,CD337,NKp30,1C7,LY117,MALS

表达区间及表达系统(Source)

Human NKp30, His Tag (NC3-H5228) is expressed from human 293 cells (HEK293). It contains AA Leu 19 - Gly 135 (Accession # AAH52582).

Predicted N-terminus: Leu 19

蛋白结构(Molecular Characterization)

Online(Leu 19 -  Gly 135) AAH52582

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 13.7 kDa. The protein migrates as 21-32 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)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Protocol

 

背景(Background)

Natural cytotoxicity triggering receptor 3 (NCR3) is also known as Activating natural killer receptor p30, Natural killer cell p30-related protein (NK-p30), CD antigen CD337, 1C7, LY117. NCR3 /CD337 /NKp30 belongs to the natural cytotoxicity receptor (NCR) family. NCR3 /NKp30 contains one Ig-like (immunoglobulin-like) domain. NCR3 /NKp30 is selectively expressed by all resting and activated NK cells and weakly expressed in spleen. NCR3 is homodimer in the unliganted form. NCR3 interacts with CD3Z. NCR3 interacts with and is activated by binding to NCR3LG1 or BAG6. Engagement of NCR3 by BAG6 also promotes dendritic cell (DC) maturation, both through killing those DCs that did not properly acquire a mature phenotype, and inducing NK cells to release TNFA and IFNG, which promotes DC maturation.
