Serpinh1. also known as heat shock protein 47 (HSP47), is a stress-inducible molecular chaperone belonging to the serine protease inhibitor (serpin) superfamily. Unlike most serpins, it lacks protease inhibitory activity and instead plays a critical role in collagen biosynthesis. Primarily expressed in collagen-producing cells (e.g., fibroblasts, osteoblasts), Serpinh1 binds to nascent procollagen chains in the endoplasmic reticulum, ensuring their proper folding, stabilization, and triple-helix formation. This interaction is pH-dependent, with dissociation occurring in the Golgi apparatus prior to collagen secretion.
The protein’s structure includes a conserved serpin domain and a unique C-terminal region essential for collagen binding. Dysregulation of Serpinh1 is linked to fibrosis, cancer metastasis, and connective tissue disorders like osteogenesis imperfecta. Its overexpression in fibrotic tissues (e.g., liver, lung) correlates with excessive collagen deposition, while mutations cause collagen misfolding in hereditary skeletal diseases.
Recombinant Serpinh1 proteins are engineered using bacterial (E. coli) or mammalian expression systems, often tagged with histidine or GST for purification. These recombinant forms enable studies on collagen assembly mechanisms, drug screening for antifibrotic therapies, and structural analysis of chaperone-collagen interactions. Researchers also utilize them to model diseases or develop targeted inhibitors to block pathological collagen overproduction. As a biomarker and therapeutic target, Serpinh1 continues to bridge fundamental cell biology and translational research in extracellular matrix-related pathologies.
