Biological background
CD276 (protein: Lysosome-associated membrane glycoprotein 2 (Lamp2)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): May participate in the regulation of T-cell-mediated immune response. May play a protective role in tumor cells by inhibiting natural-killer mediated cell lysis as well as a role of marker for detection of neuroblastoma cells. May be involved in the development of acute and chronic transplant rejection and in the regulation of lymphocytic activity at mucosal surfaces. Could also play a key role in providing the placenta and fetus with a suitable immunological environment throughout pregnancy. Both isoform 1 and isoform 2 appear to be redundant in their ability to modulate CD4 T-cell responses. Isoform 2 is shown to enhance the induction of cytotoxic T-cells and selectively stimulates interferon gamma production in the presence of T-cell receptor signaling. . Reported cellular localization context: Membrane ; Single-pass type I membrane protein . Tissue expression notes (as provided): Ubiquitous but not detectable in peripheral blood lymphocytes or granulocytes. Weakly expressed in resting monocytes. Expressed in dendritic cells derived from monocytes. Expressed in epithelial cells of sinonasal tissue. Expressed in extravillous trophoblast cells and Hofbauer cells of the first trimester placenta and term placenta. .
Research relevance and current trends
- Research context keywords from the source record include: Adaptive Immunity,Cancer,Hematopoietic Progenitors,Immunology,Lymphoid,Stem Cells,T Cells,T Lymphocytic Lineage,Tumor Biomarkers.
- 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.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
- Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.
Workflow ideas (metafield): Validate CD276 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CD276 expression by Western blot in cell or tissue lysates, Quantify CD276-positive cells by flow cytometry in single-cell suspensions, Enrich CD276 by immunoprecipitation from lysates for downstream analysis
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: 90 kDa; calculated MW: 57235 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
