The CTHRC1 protein also known as Collagen Triple Helix Repeat Containing 1 is a secreted protein with a mass of approximately 28 kDa. It plays a mechanical role in the extracellular matrix by modulating collagen fibrillogenesis and cross-linking. Increased expression of CTHRC1 protein often appears in areas undergoing active remodeling like those around wound healing sites fibrotic lesions and certain tumor tissues. The expression is not uniform across tissues and often corresponds to areas requiring structural reorganization or repair.

Biological function summary

CTHRC1 impacts cell migration and invasion. It associates with several extracellular matrix components influencing cellular response through cytoskeletal reorganization. There is no evidence for its participation as a part of a larger protein complex. The modulation of collagen interactions by CTHRC1 enables it to play a significant role in angiogenesis and tissue repair processes affecting endothelial and fibroblast cell functions.

Pathways

CTHRC1 participates in signaling pathways related to Transforming Growth Factor-beta (TGF-β) and Wnt. In the TGF-β pathway it impacts cellular responses to growth signals enhancing remodeling and repair mechanisms. Through the Wnt signaling pathway CTHRC1 interacts with Dishevelled proteins assisting in regulation and pathway activation related to cell proliferation and migration. These pathways highlight its involvement in important biological processes that influence tissue structure and cell communication.

CTHRC1 has relevance to both cancer progression and fibrotic diseases. Its overexpression is often noted in breast cancer where it drives tumor growth and metastasis interacting with other matrix components. Similarly in fibrosis CTHRC1 contributes to excessive collagen deposition and tissue stiffness. Proteins like TGF-β intersect with CTHRC1 functions further modulating disease pathway outcomes. Understanding CTHRC1's role in these disorders could inform therapeutic targets for modulating matrix dynamics.
