JAM2 (junctional adhesion molecule 2), JAMB or CD322 is a 298 amino acid (aa) single pass type I transmembrane glycoprotein that belongs to the Immunoglobulin superfamily (IgSF).  JAM2 contains an N-terminal signal peptide, a 210-aa extracellular domain (ECD) with 2 Ig-like V-type domains and 3 potential glycosylation sites, a transmembrane domain (TM), and a 39-aa short cytoplasmic tail. JAM2 is localized at the tight junctions of both epithelial and endothelial cells. JAM2 heterodimerizes with JAM3.  JAM2 acts as an adhesive ligand for interacting with a variety of immune cell types, and may play a role in lymphocyte homing to secondary lymphoid organs.

Product Details

 

Gene Symbol: JAM2; JAMB; CD322; JAM-B; VEJAM; PRO245; VE-JAM; C21orf43

 

NCBI Gene ID: 58494

 

Uniprot Entry: P57087

 

Construct Details: Full length human JAM2/CD322 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: 897 (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.
