LAMP2 (Lysosome-associated membrane glycoprotein 2) or CD107b is a single pass type I transmembrane glycoprotein belonging to the LAMP family. LAMP2 contains 2 extracellular lumenal domains, a transmembrane and a cytoplasmic domain.  LAMP2 may present carbohydrate ligands to selectins and is implicated in tumor cell metastasis.  LAMP2 may also function in the protection, maintenance, and adhesion of the lysosome. LAMP2 plays an important role in chaperone-mediated autophagy, a process that mediates lysosomal degradation of proteins in response to various stresses and as part of the normal turnover of proteins with a long biological half-live.  LAMP2 is required for efficient MHCII-mediated presentation of exogenous antigens via its function in lysosomal protein degradation; antigenic peptides generated by proteases in the endosomal/lysosomal compartment are captured by nascent MHCII subunits.  Mutations in the LAMP2 gene are associated with Danon disease (DAND), a lysosomal glycogen storage disease characterized by the clinical triad of cardiomyopathy, vacuolar myopathy and mental retardation. DAND is often associated with an accumulation of glycogen in muscle and lysosomes.

Product Details

 

Gene Symbol: LAMP2; CD107b; LAMPB; LGP96; CD107-b; LAMP-2; LGP-96; LGP110

 

NCBI Gene ID: 3920

 

Uniprot Entry: P13473

 

Construct Details: Full length human LAMP2 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without an antibiotic 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: 1233 (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.
