Heat shock protein 47, also known as SERPINH1 is a serpin which serves as a human chaperone protein for collagen.[5][6]

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]
