**Background of HGFAC Recombinant Protein**
Hepatocyte Growth Factor Activator (HGFAC) is a serine protease that plays a critical role in activating hepatocyte growth factor (HGF), a key regulator of cell proliferation, motility, and tissue regeneration. HGFAC is synthesized as an inactive zymogen (pro-HGFAC) and undergoes proteolytic cleavage to become enzymatically active. This activation process is essential for converting the inactive pro-HGF into its mature, biologically active form (HGF), which binds to the c-Met receptor to initiate downstream signaling pathways involved in wound healing, organ development, and cancer progression.
HGFAC is primarily produced in the liver and is implicated in various physiological and pathological processes, including liver regeneration, angiogenesis, and tumor metastasis. Dysregulation of HGFAC activity has been linked to diseases such as hereditary angioedema, fibrosis, and certain cancers.
Recombinant HGFAC protein is generated using biotechnological methods, often through expression in mammalian cell systems (e.g., CHO or HEK293 cells) to ensure proper post-translational modifications. The recombinant form retains the enzymatic activity of native HGFAC, enabling its use in research and therapeutic applications. It serves as a vital tool for studying the HGF/c-Met axis, screening inhibitors, or developing treatments for conditions involving impaired tissue repair or abnormal HGF signaling.
In therapeutic contexts, recombinant HGFAC holds potential for enhancing tissue regeneration or modulating pathological processes, though clinical applications remain under investigation. Its production in a controlled, scalable manner ensures high purity and consistency, addressing challenges associated with isolating the protein from natural sources. Overall, HGFAC recombinant protein is a valuable resource for advancing both basic research and translational medicine.
