IgSF2 or EWI3 is a 1194 amino acid (aa) single pass type I transmembrane glycoprotein that belongs to the EWI subfamily of the Immunoglobulin superfamily (IgSF).  IgSF3 contains an N-terminal signal peptide, a 1105-aa extracellular domain (ECD) with 8 Ig-like C2-type domains, an EWI (Glu-Trp-Ile)-motif and 5 potential glycosylation sites, a transmembrane domain (TM), and a 49-aa cytoplasmic tail. IThere is likely an interchromosomal Alu-mediated fusion between IGSF3 on 1p13.1 and GGT on 22q11.2.  A mutation in the IgSF3 gene has been associated with bilateral nasolacrimal duct obstruction (LCDD), a condition resulting in the imbalance between tear production and tear drainage caused by failure of the nasolacrimal duct to open into the inferior meatus.

Product Details

 

Gene Symbol: IgSF3; EWI3; V8; LCDD; EWI-3; IGSF-3

 

NCBI Gene ID: 3321

 

Uniprot Entry: O75054

 

Construct Details: Full length human IgSF3 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: 3585 (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.
