JAM3 (Junctional adhesion molecule 3) orJAMC is a 310 amino acid (aa) single pass type I transmembrane glycoprotein that belongs to the Immunoglobulin superfamily (IgSF).  JAM3 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 48-aa short cytoplasmic tail. JAM3 is localized in the tight junctions between high endothelial cells. Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. JAM3 acts as a receptor for another member of this family JAM2, which togther form a heterodimer.  JAM3 participates in cell-cell adhesion as a counter-receptor for ITGAM, mediating leukocyte-platelet interactions and is involved in the regulation of transepithelial migration of polymorphonuclear neutrophils (PMN). The soluble form of JAM3 is thought to be a mediator of angiogenesis. A mutation in an intron of the JAM3 gene is associated with hemorrhagic destruction of the brain, subependymal calcification, and congenital cataracts (HDBSCC).

Product Details

 

Gene Symbol: JAM3; JAMC; JAM-3; JAM-C

 

NCBI Gene ID: 83700

 

Uniprot Entry: Q9BX67

 

Construct Details: Full length human JAM3 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: 933 (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.
