Recombinant Mouse ZNRF3 Protein, N-His

Introduction

Recombinant Mouse ZNRF3 Protein is a highly purified and bioactive protein that is produced through recombinant DNA technology. This protein is a member of the ZNRF family of E3 ubiquitin ligases and plays a crucial role in regulating the Wnt signaling pathway. It is commonly used as an antigen in various research studies and has diverse applications in the fields of cell biology, biochemistry, and immunology.

Structure of Recombinant Mouse ZNRF3 Protein

The recombinant mouse ZNRF3 protein is a 54 kDa protein consisting of 476 amino acids. It contains a RING finger domain, a transmembrane domain, and a C-terminal cytoplasmic domain. The RING finger domain is responsible for the E3 ubiquitin ligase activity of ZNRF3, while the transmembrane domain anchors the protein to the cell membrane. The cytoplasmic domain is involved in the interaction with other proteins in the Wnt signaling pathway.

Activity of Recombinant Mouse ZNRF3 Protein

The primary activity of recombinant mouse ZNRF3 protein is its role as an E3 ubiquitin ligase. This means that it catalyzes the transfer of ubiquitin molecules onto specific target proteins, leading to their degradation by the proteasome. ZNRF3 specifically targets Frizzled receptors, which are key components of the Wnt signaling pathway. By promoting the degradation of Frizzled receptors, ZNRF3 acts as a negative regulator of the Wnt signaling pathway.

Additionally, studies have shown that ZNRF3 also has a role in regulating the activity of other signaling pathways, such as the Notch and Hedgehog pathways. It has been found to interact with several proteins involved in these pathways, suggesting a broader role for ZNRF3 in cellular signaling.

Applications of Recombinant Mouse ZNRF3 Protein

1. Research on Wnt Signaling Pathway

Recombinant mouse ZNRF3 protein is commonly used as an antigen in studies related to the Wnt signaling pathway. It is used to investigate the role of ZNRF3 in regulating this pathway and its interactions with other components of the pathway. The protein can also be used to study the effects of ZNRF3 mutations on Wnt signaling and its implications in diseases such as cancer.

2. Protein-Protein Interaction Studies

As ZNRF3 interacts with various proteins in different signaling pathways, recombinant mouse ZNRF3 protein is a valuable tool for studying protein-protein interactions. It can be used in techniques such as co-immunoprecipitation and yeast two-hybrid assays to identify and characterize the binding partners of ZNRF3.

3. Drug Target Identification

Given the crucial role of ZNRF3 in regulating the Wnt signaling pathway, it has emerged as a potential drug target for diseases such as cancer. Recombinant mouse ZNRF3 protein can be used in high-throughput screening assays to identify small molecule inhibitors that can modulate its activity. This can aid in the development of novel therapeutic strategies for Wnt-related diseases.

4. Cell Signaling Studies

Recombinant mouse ZNRF3 protein can also be used in cell signaling studies to investigate the effects of ZNRF3 on cellular processes. It can be used to study the downstream effects of ZNRF3-mediated degradation of Frizzled receptors and its impact on cell proliferation, differentiation, and migration.
