JAM4 (Junctional adhesion molecule 4) or IgSF5 is a 407 amino acid (aa) single pass type I transmembrane glycoprotein that belongs to the Immunoglobulin superfamily (IgSF).  JAM4 contains an N-terminal signal peptide, a 266-aa extracellular domain (ECD) with 2 Ig-like V-type domains and 4 potential glycosylation sites, a transmembrane domain (TM), and a 122-aa cytoplasmic tail. JAM4 provides, together with MAGI1, an adhesion machinery at tight junctions, which may regulate the permeability of kidney glomerulus and small intestinal epithelial cells. JAM4 mediates calcium-independent homophilic cell adhesion. In testis, it may function as a cell adhesion molecule rather than a tight-junction protein. JAM4may participate in the adhesion between spermatogonia-spermatogonia, spermatogonia-Sertoli cells, and Sertoli cells-Sertoli cells.

Product Details

 

Gene Symbol: JAM4; IgSF5; GSF5; JAM-4

 

NCBI Gene ID: 150084

 

Uniprot Entry: Q9NSI5

 

Construct Details: Full length human JAM4 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: 1224 (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.
