Biological background
EPAS1 (protein: Glycogen synthase kinase-3 beta (gsk3b)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Transcription factor involved in the induction of oxygen regulated genes. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. Regulates the vascular endothelial growth factor (VEGF) expression and seems to be implicated in the development of blood vessels and the tubular system of lung. May also play a role in the formation of the endothelium that gives rise to the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase expression. Activation seems to require recruitment of transcriptional coactivators such as CREBPB and probably EP300. Interaction with redox regulatory protein APEX seems to activate CTAD. Reported cellular localization context: Nucleus . Nucleus speckle . Colocalizes with HIF3A in the nucleus and speckles. . Tissue expression notes (as provided): Expressed in most tissues, with highest levels in placenta, lung and heart. Selectively expressed in endothelial cells.
Research relevance and current trends

- 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.
- Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
Workflow ideas (metafield): Validate EPAS1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect EPAS1 expression by Western blot in cell or tissue lysates, Localize EPAS1 by immunofluorescence/immunocytochemistry in cultured cells, Quantify EPAS1-positive cells by flow cytometry in single-cell suspensions
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: 80 kDa; calculated MW: 96459 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
