產(chǎn)品描述：
Recombinant Mouse Triggering receptor expressed on myeloid cells 2 (Trem2) with an N-terminal 6xHis-tag is a partial-length protein expressed in the mammalian cells. The sequence used to prepare this recombinant Trem2 protein corresponds to the extracellular domain (Leu19-Ser171) of mouse Trem2. Its purity is greater than 90% as determined by SDS-PAGE. A molecular mass band of approximately 23 kDa was visualized on the reducing SDS-PAGE gel. This recombinant Trem2 protein may find uses in the specific antibody production or the studies of Trem2-mediated immunology.
Trem2 is a transmembrane protein expressed in the microglia, alveolar macrophages, osteoclasts, and other mononuclear phagocytes. Once activated by its ligands including anionic lipids (LPS and phospholipids), apolipoprotein J (ApoJ), and ApoE, Trem2 recruits tyrosine kinase SYK through the DNAX-activating protein of 12 kDa (DAP12). Multiple signaling pathways including MAPK and PI3K pathways ensue, modulating the phagocytosis of cellular debris and the inflammatory responses of microglia. LucineKaranfilian etc. demonstrated that Trem2 regulates the composition and deposition of amyloid plaque, microglial morphology and proliferation, neuroinflammation, and tau phosphorylation. As a sensor for anionic lipids exposed during neuronal apoptosis and Aβ deposition, Trem2 may improve spatial abilities and memory, and protect against apoptosis.

功能：Forms a receptor signaling complex with TYROBP which mediates signaling and cell activation following ligand binding. Acts as a receptor for amyloid-beta protein 42, a cleavage product of the amyloid-beta precursor protein APP, and mediates its uptake and degradation by microglia. Binding to amyloid-beta 42 mediates microglial activation, proliferation, migration, apoptosis and expression of pro-inflammatory cytokines, such as IL6R and CCL3, and the anti-inflammatory cytokine ARG1. Acts as a receptor for lipoprotein particles such as LDL, VLDL, and HDL and for apolipoproteins such as APOA1, APOA2, APOB, APOE, APOE2, APOE3, APOE4, and CLU and enhances their uptake in microglia. Binds phospholipids (preferably anionic lipids) such as phosphatidylserine, phosphatidylethanolamine, phosphatidylglycerol and sphingomyelin. Regulates microglial proliferation by acting as an upstream regulator of the Wnt/beta-catenin signaling cascade. Required for microglial phagocytosis of apoptotic neurons. Also required for microglial activation and phagocytosis of myelin debris after neuronal injury and of neuronal synapses during synapse elimination in the developing brain. Regulates microglial chemotaxis and process outgrowth, and also the microglial response to oxidative stress and lipopolysaccharide. It suppresses PI3K and NF-kappa-B signaling in response to lipopolysaccharide; thus promoting phagocytosis, suppressing pro-inflammatory cytokine and nitric oxide production, inhibiting apoptosis and increasing expression of IL10 and TGFB. During oxidative stress, it promotes anti-apoptotic NF-kappa-B signaling and ERK signaling. Plays a role in microglial MTOR activation and metabolism. Regulates age-related changes in microglial numbers. Triggers activation of the immune responses in macrophages and dendritic cells. Mediates cytokine-induced formation of multinucleated giant cells which are formed by the fusion of macrophages. In dendritic cells, it mediates up-regulation of chemokine receptor CCR7 and dendritic cell maturation and survival. Involved in the positive regulation of osteoclast differentiation.
