**Background of MST Recombinant Protein**
MST (Macrophage Stimulating Protein), also known as MSP or hepatocyte growth factor-like protein, is a plasminogen-related growth factor involved in regulating immune responses, tissue repair, and cellular homeostasis. It is primarily produced by hepatocytes and circulates as an inactive precursor (pro-MSP) that requires proteolytic cleavage for activation. The mature MST protein is a heterodimer composed of α and β chains linked by disulfide bonds, with structural homology to hepatocyte growth factor (HGF).
Biologically, MST binds to the RON (Receptor d’Origine Nantais) tyrosine kinase receptor, predominantly expressed on macrophages, epithelial cells, and certain cancer cells. Activation of RON triggers downstream signaling pathways, including MAPK, PI3K-Akt, and NF-κB, which regulate processes such as cell migration, inflammation, and survival. MST-RON signaling plays dual roles: it promotes tissue repair by modulating macrophage phagocytosis and resolving inflammation, yet aberrant activation is linked to pathological conditions, including cancer progression, fibrosis, and chronic inflammatory diseases.
Recombinant MST proteins are engineered using expression systems (e.g., mammalian CHO cells) to ensure proper post-translational modifications and bioactivity. These proteins are critical tools for studying RON-mediated mechanisms and developing therapeutic strategies. For instance, MST-based inhibitors or RON-targeted antibodies are explored to block oncogenic signaling, while recombinant MST itself may aid in regenerative therapies by enhancing tissue repair.
Overall, MST recombinant proteins bridge fundamental research and clinical applications, offering insights into cellular signaling dynamics and potential interventions for diseases driven by dysregulated MST-RON pathways.
