IgSF2 or CD101 is a 1021 amino acid (aa) single pass type I transmembrane glycoprotein that belongs to the EWI subfamily of the Immunoglobulin superfamily (IgSF).  IgSF2 contains an N-terminal signal peptide, a 934-aa extracellular domain (ECD) with 7 Ig-like C2-type domains, an EWI (Glu-Trp-Ile)-motif and 2 potential glycosylation sites, a transmembrane domain (TM), and a 46-aa cytoplasmic tail. IgSF2 plays a role as inhibitor of T-cells proliferation induced by CD3 via IL-10 secretion by cutaneous dendritic cells. IgSF2 inhibits expression of IL2RA on activated T-cells and secretion of IL2. IgSF2 inhibits tyrosine kinases that are required for IL2 production and cellular proliferation. It also inhibits phospholipase C-gamma-1/PLCG1 phosphorylation and subsequent CD3-induced changes in intracellular free calcium. IgSF2 prevents nuclear translocation of nuclear factor of activated T-cell (NFAT) to the nucleus. IgSF2 may be a marker of CD4+ CD56+ leukemic tumor cells.

Product Details

 

Gene Symbol: IgSF2; CD101; EWI101; V7; EWI-101; IGSF-2

 

NCBI Gene ID: 9398

 

Uniprot Entry: Q93033

 

Construct Details: Full length human IgSF2/CD101 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: 3066 (bp)
