Function
This protein is a member of the serpin superfamily of serine proteinase inhibitors. Its expression is induced by heat shock. HSP47 is expressed in the endoplasmic reticulum. These cells synthesize and secrete type I and type II collagen. [7] The protein localizes to the endoplasmic reticulum lumen and binds collagen; thus it is thought to be a molecular chaperone involved in the maturation of collagen molecules. Autoantibodies to this protein have been found in patients with rheumatoid arthritis.[5]
Interactions
Heat shock protein 47 has been shown to interact with collagens I, II, III, IV and V.[8]
Research on role in preventing deep vein thrombosis
Research published in 2023 indicates a potential role of HSP47 regarding deep vein thrombosis.[9] [10] This initial research will be followed by additional studies.
