Biological background
Recent studies have shown that PDZD8 acts as a functional ortholog of yeast Mmm1-Mdm12 complex components in establishing ER-mitochondrial contacts. By bridging the two organelles, PDZD8 helps coordinate mitochondrial dynamics and calcium uptake during neuronal signaling and metabolic activity. Loss of PDZD8 disrupts mitochondrial morphology, impairs synaptic transmission, and affects neuronal energy balance, highlighting its importance in brain physiology. The protein is also implicated in autophagy regulation, as it contributes to the spatial organization of membrane contact sites during autophagosome formation.
The PDZD8 gene is located on chromosome 10q25.3 and encodes multiple isoforms through alternative splicing. The protein localizes to the ER membrane via its C-terminal transmembrane domain and interacts with small GTPases and lipid transport proteins. Dysregulation of PDZD8 has been associated with neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and Huntington's disease, where altered organelle tethering and calcium imbalance contribute to pathogenesis.
Immunohistochemical staining using PDZD8 antibody reveals perinuclear and cytoplasmic localization in neurons, hepatocytes, and fibroblasts. The antibody is valuable for investigating ER-mitochondrial contact formation, calcium signaling, and membrane lipid metabolism. PDZD8 antibody from
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.
- Immunofluorescence: visualize subcellular distribution and cell-to-cell heterogeneity.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
- Flow cytometry: quantify target-positive populations and signal shifts at single-cell resolution.
- ELISA: support antibody-based quantification in assay formats where applicable.
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.
