MET, a receptor tyrosine kinase encoded by the *MET* proto-oncogene, plays a pivotal role in regulating cellular processes such as proliferation, migration, and survival. It is activated by its ligand, hepatocyte growth factor (HGF), initiating downstream signaling pathways like MAPK/ERK and PI3K/AKT. Dysregulation of MET signaling—through overexpression, gene amplification, or mutations—is strongly implicated in tumorigenesis, metastasis, and drug resistance across cancers, including non-small cell lung cancer (NSCLC), gastric cancer, and renal cell carcinoma.
Recombinant MET proteins are engineered versions of the MET receptor or its domains, produced using expression systems like mammalian, insect, or bacterial cells. These proteins typically retain functional epitopes for ligand binding or antibody recognition, enabling applications in drug discovery and biomedical research. For instance, MET extracellular domain (ECD) recombinants are widely used to study HGF-MET interactions, screen therapeutic antibodies, or develop diagnostic assays. Fc-fused MET variants enhance stability and simplify detection in binding studies.
In therapeutic development, MET recombinant proteins serve as critical tools for validating MET-targeted therapies, such as tyrosine kinase inhibitors (TKIs) or monoclonal antibodies. They also aid in elucidating resistance mechanisms, such as MET amplification in EGFR inhibitor-resistant NSCLC. Additionally, MET recombinants are employed in structural studies to resolve MET-HGF complex architectures, guiding the design of next-generation inhibitors.
Overall, MET recombinant proteins bridge basic research and clinical translation, offering insights into MET biology and accelerating the development of precision oncology therapies. Their versatility underscores their importance in understanding MET-driven pathologies and advancing targeted cancer interventions.
