TREM2 (Triggering receptor expressed on myeloid cells 2)  is a single pass type I transmembrane glycoprotein that belongs to the Immunoglobulin superfamily (IgSF) with 1 Ig-like V-type domain in the extracellular region.  TREM2 forms a receptor signaling complex with the TYROBP (TYRO protein tyrosine kinase binding protein), which mediates signaling and cell activation following ligand binding.  TREM2 triggers activation of the immune responses in macrophages and dendritic cell to produce constitutive inflammatory cytokines. TREM2 also acts as a receptor for amyloid-beta protein 42 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.  TREM2 is  required for microglial phagocytosis of apoptotic neurons and myelin debris after neuronal injury.  TREM2 also acts as a receptor for lipoprotein particles and for apolipoproteins.  Defects in the TREM2 gene are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy 2 (PLOSL2), an autosomal recessive disease characterized by presenile frontal dementia.

Product Details

 

Gene Symbol: TREM2; TREM-2; PLOSL2; Trem2a; Trem2b; Trem2c

 

NCBI Gene ID: 54209

 

Uniprot Entry: Q9NZC2

 

Construct Details: Full length human TREM2 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 693 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
