Biological background

DSG2 (protein: Lysosome-associated membrane glycoprotein 2 (Lamp2)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Involved in melanosome biogenesis by ensuring the stability of GPR143. Plays a vital role in the expression, stability, trafficking, and processing of melanocyte protein PMEL, which is critical to the formation of stage II melanosomes. . Reported cellular localization context: Endoplasmic reticulum membrane; Single-pass type III membrane protein. Golgi apparatus. Golgi apparatus, trans-Golgi network membrane. Melanosome. Also found in small vesicles and tubules dispersed over the entire cytoplasm. A small fraction of the protein is inserted into the membrane in an inverted orientation. Inversion of membrane topology results in the relocalization of the protein from a predominant Golgi/post- Golgi area to the endoplasmic reticulum. Melanoma cells expressing the protein with an inverted membrane topology are more effectively recognized by specific cytolytic T-lymphocytes than those expressing the protein in its native membrane orientation. Tissue expression notes (as provided): Expression is restricted to melanoma and melanocyte cell lines and retina.

Research relevance and current trends

• Research context keywords from the source record include: Cadherins,Cancer,Cardiovascular,Cell Adhesion,Cytoskeleton/ECM,Invasion/Microenvironment,Signal Transduction.
• Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
• Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.

Common research applications

• Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
• Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.

Workflow ideas (metafield): Validate DSG2 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect DSG2 expression by Western blot in cell or tissue lysates, Detect DSG2 in FFPE tissue sections by immunohistochemistry, Localize DSG2 by immunofluorescence/immunocytochemistry in cultured cells, Quantify DSG2-positive cells by flow cytometry in single-cell suspensions

Notes for experimental interpretation

• Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
• Apparent molecular weight may vary by sample type and processing (observed MW: 42 kDa; calculated MW: 13157 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
