  • Function

    Implicated in tumor cell metastasis. May function in protection of the lysosomal membrane from autodigestion, maintenance of the acidic environment of the lysosome, adhesion when expressed on the cell surface (plasma membrane), and inter-and intracellular signal transduction. Protects cells from the toxic effects of methylating mutagens.
  • Tissue specificity

    Isoform LAMP-2A is highly expressed in placenta, lung and liver, less in kidney and pancreas, low in brain and skeletal muscle. Isoform LAMP-2B is highly expressed in skeletal muscle, less in brain, placenta, lung, kidney and pancreas, very low in liver.
  • Involvement in disease

    Defects in LAMP2 are the cause of Danon disease (DAND) [MIM:300257]; also known as glycogen storage disease type 2B (GSD2B). DAND is a lysosomal glycogen storage disease characterized by the clinical triad of cardiomyopathy, vacuolar myopathy and mental retardation. It is often associated with an accumulation of glycogen in muscle and lysosomes.
  • Sequence similarities

    Belongs to the LAMP family.
  • Post-translational

    O- and N-glycosylated; some of the 16 N-linked glycans are polylactosaminoglycans.
  • Cellular localization

    Cell membrane. Endosome membrane. Lysosome membrane. This protein shuttles between lysosomes, endosomes, and the plasma membrane.
  • Information by UniProt

  • Form

    Alternative splicing produces 3 isoforms.

  • Immunofluorescence analysis of mouse A20 B cells, staining LAMP2 with ab25339.

    Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 5% serum for 1 hour at 25°C. Samples were incubated with primary antibody (1/100 in 5% FCS in PBS) for 24 hours at 4°C. A FITC-conjugated goat anti-rat polyclonal IgG (1/500) was used as the secondary antibody.

  • ab25339 staining LAMP2 from mouse liver cells by Immunohistochemistry (Frozen sections). The fresh tissue was cut into small pieces, put into OCT, and frozen in liquid nitrogen. 5µm sections were prepared using a cyrostat. The tissue section was fixed in 5% paraformaldehyde and blocked in 5% serum with 0.05% saponin to increase the permeability. The sample was incubated with ab25339 (1/100 dilution) overnight, and incubated with secondary antibody (Cy2 conjugated donkey anti-rat IgG) for 2 hours. After staining with DAPI (1/1000 dilution) for 2 minutess, the section was mounted.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 45 kDa
    Additional bands at: 120 kDa (possible post-translational modification), 90 kDa (possible post-translational modification)

    Exposure time: 20 minutes

    This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system under denaturing, reducing conditions. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes.  After transfer, the membrane was blocked for an hour in 2% BSA before being incubated overnight at 4°C with a rat monoclonal [ABL-93] to LAMP2 (ab25339; diluted 1:1000). Antibody binding was detected using peroxidase labelled goat anti-rat IgG (diluted 1:10000) for an hour at room temperature and visualised using ECL development solution (20 minutes exposure).

  • Overlay histogram showing RAW 264.7 cells stained with ab25339 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab25339, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rat IgG (H+L) (ab98386) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rat IgG2a, kappa monoclonal [aRTK2758] (ab18450, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in RAW 264.7 cells fixed with 80% methanol/permeabilized in 0.1% PBS-Tween used under the same conditions.

  • ICC/IF image of ab25339 stained RAW246.7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab25339, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96887, DyLight® 488 goat anti-rat IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
