Introduction of AMOT
Angiomotin (AMOT) is a critical transmembrane scaffold protein frequently dysregulated across diverse solid tumors. Characterized by alternative splicing, it primarily manifests as two functional isoforms: the 130 kDa (p130) variant, which contains an extended N-terminal domain for F-actin binding, and the 80 kDa (p80) variant.

Beyond its structural role in maintaining tight junction integrity, AMOT is a master regulator of the Hippo signaling pathway, influencing the nuclear translocation of YAP/TAZ. Growing evidence confirms that AMOT dictates pathological trajectories in tumor proliferation, apoptosis evasion, and invasive angiogenesis, making its precise quantification essential for prognostic and therapeutic development.

Applications
Oncology Drug Discovery & Target Validation
AMOT serves as a critical target for small molecules and monoclonal antibodies aiming to disrupt YAP-driven tumor growth. Our analysis identifies lead compounds that successfully inhibit transcriptional activity by sequestering YAP in the cytoplasm or preventing its nuclear translocation.
Vascular Biology & Pathological Angiogenesis
Researchers utilize precise AMOT profiling to study endothelial cell migration, polarization, and capillary tube formation. These insights are essential for developing next-generation anti-angiogenic therapies for conditions like age-related macular degeneration and hyper-vascularized solid tumors.
Precision Diagnostic Biomarker Development
Quantitative AMOT levels in liquid biopsies, including circulating tumor cells and exosomes, are being rigorously explored as high-fidelity prognostic indicators for metastatic potential and disease recurrence in breast, prostate, and hepatic carcinomas.
Hippo pathway Mechanotransduction Mapping
Comprehensive AMOT analysis provides a robust read-out for Hippo pathway activity. We help researchers decode the complex mechanotransduction signals that regulate organ size, tissue regeneration, and the bypass of contact inhibition in cancer models.

FAQs
-
Q: Can your platform distinguish between the p130 and p80 isoforms in a single tissue sample?
A: Yes. We utilize multiplexed immunofluorescence and isoform-specific Western blotting. By targeting the unique N-terminal domain present only in the p130 variant, we can provide precise quantification of each isoform's relative abundance within the same lysate or tissue section.
-
Q: What is the primary challenge in maintaining AMOT-TNKS interactions during analysis?
A: These interactions are often transient and sensitive to lysis buffers. We utilize specialized cross-linking protocols and optimized mild detergents that stabilize the protein complex without disrupting the binding epitopes required for our interaction assays.
-
Q: Are your AMOT antibodies suitable for use in Flow Cytometry (FACS)?
A: Absolutely. Our benchmark mAbs are validated for intracellular staining, allowing you to correlate AMOT expression levels with specific phases of the cell cycle or surface marker expression in heterogeneous cell populations.
-
Q: Can I provide formalin-fixed paraffin-embedded (FFPE) slides for AMOT analysis?
A: We accept FFPE samples and employ advanced heat-induced epitope retrieval (HIER) techniques specifically calibrated for the AMOT transmembrane structure to ensure high-fidelity immunohistochemical staining.
-
Q: Does Creative Biolabs offer custom inhibitory mAb development for AMOT-targeted therapy research?
A: We do. We can generate and express benchmark inhibitory antibodies in mammalian cell lines, which are suitable for functional assays, affinity binding studies, and early-stage animal model development.
