Biological background
MS4A4E is encoded by the MS4A4E gene located on human chromosome 11q12.2, within a gene cluster that includes MS4A1 (CD20), MS4A2 (Fc epsilon R1 beta), and several related family members. These proteins are often expressed in immune and epithelial tissues and are implicated in signal transduction pathways associated with receptor activation. MS4A4E is particularly abundant in microglia and macrophages, where it may modulate inflammatory responses and phagocytosis. Studies suggest that it could also play a role in neuronal-glial communication, making it a candidate gene of interest in neuroimmunology and Alzheimer's disease research.
The MS4A4E antibody is useful for western blotting, immunohistochemistry, and flow cytometry applications. Immunostaining shows membrane localization with enrichment at lipid raft domains, consistent with its predicted role in membrane signaling complexes. Research indicates that MS4A4E may interact with adaptor proteins and kinases, forming multi-protein assemblies that regulate signal amplification following receptor engagement. Dysregulation of MS4A4E expression has been reported in inflammatory conditions and neurodegenerative disease models, underscoring its functional relevance in immune signaling and brain homeostasis.
Beyond immunological contexts, MS4A4E is also implicated in epithelial barrier integrity and intercellular adhesion. Variants in MS4A4E have been linked through genome-wide association studies to altered risk of late-onset Alzheimer's disease, likely due to its regulatory relationship with MS4A6A and TREM2 pathways involved in microglial activation. Functional studies continue to explore whether MS4A4E influences receptor trafficking or calcium mobilization during immune activation.
Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Considering isoforms and post-translational regulation when interpreting protein-level changes.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.
