Recombinant Human RNF2 Protein, N-His

Introduction

Recombinant Human RNF2 Protein is a highly purified and biologically active form of the RING finger protein 2 (RNF2), also known as Ring1b. This protein is produced through recombinant DNA technology, allowing for the expression and purification of a specific protein in large quantities. RNF2 is a key player in the regulation of gene expression and has been extensively studied for its role in various cellular processes.

Structure of Recombinant Human RNF2 Protein

Recombinant Human RNF2 Protein is a 38 kDa protein consisting of 351 amino acids. It contains a RING finger domain at its N-terminus, which is responsible for its E3 ubiquitin ligase activity. The C-terminus of RNF2 contains a chromatin-binding domain, which allows it to interact with other proteins and play a role in chromatin remodeling. The recombinant protein is produced in a mammalian expression system, ensuring proper folding and post-translational modifications.

Activity of Recombinant Human RNF2 Protein

RNF2 is a member of the Polycomb group (PcG) proteins, which are involved in the epigenetic regulation of gene expression. Specifically, RNF2 is part of the Polycomb repressive complex 1 (PRC1), which is responsible for maintaining gene silencing by promoting the ubiquitination of histone H2A. This leads to the compaction of chromatin and the repression of gene transcription. The E3 ubiquitin ligase activity of RNF2 is critical for this process, as it targets specific lysine residues on histone H2A for ubiquitination.

In addition to its role in gene silencing, RNF2 has also been implicated in other cellular processes such as DNA damage response, cell cycle regulation, and stem cell differentiation. It has been shown to interact with various proteins involved in these pathways, highlighting its multifunctional role in the cell.

Applications of Recombinant Human RNF2 Protein

The availability of highly purified and biologically active Recombinant Human RNF2 Protein has allowed for its use in various research applications. One of the main applications is in the study of gene regulation and epigenetics. The recombinant protein can be used to investigate the role of RNF2 in gene silencing and chromatin remodeling, as well as its interactions with other proteins in the PRC1 complex.

Another application of Recombinant Human RNF2 Protein is in drug discovery and development. As RNF2 has been linked to various diseases, including cancer and neurological disorders, it is a potential target for therapeutic intervention. The recombinant protein can be used in high-throughput screening assays to identify small molecules that can modulate its activity and potentially serve as lead compounds for drug development.

Furthermore, Recombinant Human RNF2 Protein can also be used in the development of diagnostic assays. As RNF2 has been shown to be dysregulated in certain diseases, its detection in patient samples could serve as a biomarker for disease diagnosis and monitoring.

Conclusion

In summary, Recombinant Human RNF2 Protein is a valuable tool for studying the structure, activity, and function of this important protein. Its use in various research applications has advanced our understanding of gene regulation and epigenetics, and has the potential to contribute to the development of novel therapeutics and diagnostic tools. As research in this field continues, the use of Recombinant Human RNF2 Protein will undoubtedly play a crucial role in furthering our knowledge and advancements in this area.
