Recombinant Mouse SFRP4 Protein, N-His-SUMO

Description of Recombinant Mouse SFRP4 Protein, N-His-SUMO

Introduction

Recombinant Mouse SFRP4 Protein, also known as Secreted Frizzled-Related Protein 4, is a highly conserved protein that belongs to the secreted Frizzled-related protein (sFRP) family. It is encoded by the Sfrp4 gene and is expressed in various tissues, including the heart, lung, and skeletal muscle. The protein is involved in the regulation of the Wnt signaling pathway, which plays a crucial role in embryonic development, tissue homeostasis, and disease progression. In this article, we will discuss the structure, activity, and application of Recombinant Mouse SFRP4 Protein.

Structure of Recombinant Mouse SFRP4 Protein

Recombinant Mouse SFRP4 Protein is a 35 kDa protein consisting of 314 amino acids. It contains a cysteine-rich domain (CRD) at the N-terminus, which is responsible for binding to Wnt ligands. The CRD is followed by a linker region and a netrin domain at the C-terminus. The netrin domain is involved in binding to heparin and heparan sulfate proteoglycans, which regulate the activity of SFRP4. The protein also contains a signal peptide at the N-terminus, which allows for secretion of the protein from cells.

Activity of Recombinant Mouse SFRP4 Protein

Recombinant Mouse SFRP4 Protein acts as a modulator of the Wnt signaling pathway by binding to Wnt ligands and preventing their interaction with Frizzled receptors. This leads to the inhibition of Wnt signaling, which is essential for the regulation of cell proliferation, differentiation, and survival. In addition, SFRP4 has been shown to interact with other signaling pathways, such as the BMP and TGF-β pathways, further highlighting its role in regulating cellular processes.

Studies have also shown that SFRP4 has anti-angiogenic activity, as it inhibits the formation of new blood vessels. This is important in cancer research, as tumor growth and metastasis depend on the formation of new blood vessels. By inhibiting angiogenesis, SFRP4 can potentially be used as a therapeutic target for cancer treatment.

Application of Recombinant Mouse SFRP4 Protein

Recombinant Mouse SFRP4 Protein has various applications in both research and clinical settings. In research, it is commonly used as a tool to study the Wnt signaling pathway and its role in various cellular processes. It can also be used to investigate the potential therapeutic effects of targeting the Wnt pathway in different diseases.

In clinical settings, SFRP4 has been identified as a potential biomarker for certain diseases. For example, increased levels of SFRP4 have been found in the serum of patients with rheumatoid arthritis, suggesting its potential as a diagnostic marker for this disease. In addition, SFRP4 has been shown to play a role in the development of osteoarthritis, making it a potential therapeutic target for this condition.

Moreover, SFRP4 has been studied in the context of cancer research. It has been shown to have both tumor-suppressive and tumor-promoting effects, depending on the type of cancer. In some cancers, such as breast and lung cancer, SFRP4 expression is associated with a better prognosis, while in others, such as ovarian and pancreatic cancer, it is associated with a poorer prognosis. This highlights the potential of SFRP4 as a prognostic marker for certain types of cancer.

Conclusion

In summary, Recombinant Mouse SFRP4 Protein is a highly conserved protein that plays a critical role in regulating the Wnt signaling pathway. Its structure, activity, and various applications make it an important protein for both research and clinical purposes. Further studies on SFRP4 may reveal its potential as a therapeutic target and diagnostic marker for various diseases, including cancer.
