Biological background

Biological context: Component of the BHC complex, a corepressor complex that represses transcription of neuron-specific genes in non-neuronal cells. The BHC complex is recruited at RE1/NRSE sites by REST and acts by deacetylating and demethylating specific sites on histones, thereby acting as a chromatin modifier. In the BHC complex, it may act as a scaffold. Inhibits KDM1A-mediated demethylation of 'Lys-4' of histone H3 in vitro, suggesting a role in demethylation regulation.

Expression and localization notes: cellular localization: Nucleus., tissue context: Highly expressed in brain. Expressed at much lower level in other tissues..

Common research applications

• Western blotting (WB): Compare AP2A2 levels across samples and conditions using appropriate loading and biological controls.
• Immunohistochemistry (IHC): Evaluate spatial distribution of AP2A2 in tissue sections, considering fixation and antigen retrieval effects.
• Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
• Flow cytometry: Quantify AP2A2-positive populations in single-cell suspensions with appropriate gating and controls.
• ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.

Notes for experimental interpretation

• Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
• Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.

Additional product notes (from provided fields)

• Background: AP-2 complex subunit alpha-2 is a protein that in humans is encoded by the AP2A2 gene. The protein encoded by this gene is a subunit of the AP-2 adaptor protein complex, which is involved in linking lipid and protein membrane components with the clathrin lattice. This interaction supports the formation of clathrin-coated vesicles, and the encoded subunit aids in the process by binding polyphosphoinositide-containing lipids in the cell membrane.
• Cross reactivity: No cross-reactivity with other proteins.
• Cellular localization: Nucleus.
• Tissue details: Highly expressed in brain. Expressed at much lower level in other tissues.
• Research category: Cancer,Cell Biology,Cytoskeleton/ECM,ECM Enzymes,Extracellular Matrix,Invasion/Microenvironment,Metalloprotease,Proteolysis/Ubiquitin,Proteolytic Enzymes,Signal Transduction
