Biological background
Functionally, DEPTOR antibody recognizes a 409-amino-acid cytoplasmic protein that negatively regulates mTOR signaling. DEPTOR binds to both mTORC1 and mTORC2 via its PDZ domain, preventing phosphorylation of downstream effectors such as S6K1 and AKT. Its expression is finely tuned by nutrient availability, growth factors, and stress stimuli. Under normal conditions, mTOR phosphorylates DEPTOR, marking it for ubiquitination and proteasomal degradation, thereby sustaining mTOR activity. Conversely, nutrient deprivation or stress increases DEPTOR levels, suppressing mTOR signaling to promote autophagy and energy conservation.
The DEPTOR gene is located on chromosome 8q24.12 and encodes a DEP and PDZ domain-containing protein that integrates environmental cues with cellular metabolic state. DEPTOR functions as a feedback regulator ensuring mTOR pathway balance. Dysregulation of DEPTOR disrupts this feedback loop, leading to aberrant cell growth and metabolic reprogramming. In cancer, overexpression of DEPTOR has been observed in multiple myeloma, where it paradoxically supports survival by maintaining AKT activation through mTORC2 inhibition.
DEPTOR antibody is used to explore cellular signaling pathways involving mTOR, autophagy, and nutrient sensing. It supports applications such as western blotting, immunoprecipitation, and fluorescence microscopy to monitor DEPTOR expression and mTOR complex association. In metabolic studies, DEPTOR serves as a marker for energy stress adaptation, linking insulin signaling and amino acid availability to cell growth control. Elevated DEPTOR expression modulates lipid biosynthesis and glucose uptake pathways, reinforcing its role in metabolic regulation.
Structurally, DEPTOR contains an N-terminal DEP domain responsible for membrane association and a C-terminal PDZ domain mediating protein-protein interactions with mTOR and associated complexes. Post-translational modifications including phosphorylation and ubiquitination govern its stability and turnover. DEPTOR also interacts with transcription factors and kinases outside the mTOR axis, expanding its regulatory network.
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.
- 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.
