Biological background
Unlike its homolog IQGAP1, which promotes oncogenic signaling, IQGAP2 functions primarily as a tumor suppressor. Research with IQGAP2 antibody has shown that loss of IQGAP2 expression is frequent in hepatocellular carcinoma and gastric cancer, where it contributes to uncontrolled proliferation and reduced cell adhesion. By interacting with Rho family GTPases, IQGAP2 regulates actin dynamics and stabilizes adherens junctions, helping maintain epithelial integrity. Loss of this regulation increases motility and invasion, linking IQGAP2 deficiency to metastatic progression.
IQGAP2 is also important in liver biology. Studies using IQGAP2 antibody have demonstrated that knockout mice develop spontaneous hepatocellular carcinoma, confirming its tumor suppressor role. In normal liver tissue, IQGAP2 interacts with beta catenin and other signaling molecules to regulate hepatocyte growth and polarity. Dysregulation of this protein contributes to abnormal signaling through pathways such as Wnt and PI3K AKT, reinforcing its significance in liver disease and cancer.
Beyond the liver, IQGAP2 contributes to immune regulation and cytoskeletal remodeling in other tissues. It has been implicated in platelet activation, immune synapse formation, and gastric mucosal stability. Research with IQGAP2 antibody continues to expand understanding of its roles in diverse systems. Importantly, reduced expression of IQGAP2 in tumors is associated with poor prognosis, making it a potential biomarker for patient stratification.
IQGAP2 antibody is applied in western blotting, immunohistochemistry, and immunofluorescence. Western blotting detects expression in liver and epithelial cell lines, while immunohistochemistry highlights its localization at cell junctions in tissues. Immunofluorescence reveals its colocalization with actin and signaling molecules, providing insights into cytoskeletal regulation. These methods ensure that IQGAP2 antibody is valuable for both fundamental and translational research.
By providing validated IQGAP2 antibody reagents,
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: Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.
