產(chǎn)品描述：

This recombinant Human CD14 is a Mammalian cell-expressed protein (Full Length of Mature Protein) with N-terminal 6xHis tag, and it's purified by affinity chromatography method with a purity of 90%+ as determined by SDS-PAGE. Mammalian cell expression system can be used to produce proteins transiently or through stable cell lines, we usually use the transient method for Mammalian cell system protein expression, where the exogenous plasmid is transferred into the cell, and the transcription and translation are directly replicated in the cell. While stable cell lines can be used over several experiments, transient production can generate large amounts of protein in one to two weeks. These transient, high-yield mammalian expression systems utilize suspension cultures and can produce gram-per-liter yields.
CD14 is a glycosylphosphatidylinositol (GPI)-anchored receptor that functions in the TLR4/MD-2 complex to initiate proinflammatory signaling events in response to gram-negative bacteria by recognizing lipopolysaccharide. CD14 has also been shown to be upregulated in tubular epithelial cells of the kidney after unilateral ureteral obstruction and during renal ischemia-reperfusion injury. Stephanie Buchheister et al. revealed that CD14 plays a protective role in inflammatory bowel disease (IBD) development by enhancing intestinal barrier function.

靶點(diǎn)詳情

功能：

Coreceptor for bacterial lipopolysaccharide. In concert with LBP, binds to monomeric lipopolysaccharide and delivers it to the LY96/TLR4 complex, thereby mediating the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Acts as a coreceptor for TLR2:TLR6 heterodimer in response to diacylated lipopeptides and for TLR2:TLR1 heterodimer in response to triacylated lipopeptides, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Binds electronegative LDL (LDL(-)) and mediates the cytokine release induced by LDL(-).
