Recombinant Human NOTCH4, N-His

Title: Introduction to Recombinant Human NOTCH4

Recombinant Human NOTCH4, also known as Notch homolog 4 or NOTCH4, is a protein that plays a crucial role in cell signaling and development. It is a transmembrane receptor protein that is encoded by the NOTCH4 gene in humans. This protein is a member of the Notch family, which consists of four receptors (NOTCH1-4) and five ligands (DLL1, DLL3, DLL4, JAG1, and JAG2). Recombinant Human NOTCH4 is produced through recombinant DNA technology and has several important structural and functional characteristics that make it a valuable tool in scientific research and medical applications.

Structure of Recombinant Human NOTCH4

Recombinant Human NOTCH4 is a single-pass transmembrane protein that consists of 2003 amino acids. It has a large extracellular domain, a transmembrane domain, and an intracellular domain. The extracellular domain contains multiple epidermal growth factor-like (EGF) repeats, which are important for ligand binding. The transmembrane domain anchors the protein to the cell membrane, while the intracellular domain contains a conserved domain known as the RAM domain, which is essential for the activation of downstream signaling pathways.

Activity of Recombinant Human NOTCH4

Recombinant Human NOTCH4 is a key regulator of cell fate decisions and plays a critical role in various cellular processes such as proliferation, differentiation, and apoptosis. It is activated by the binding of its ligands, which leads to the cleavage of the intracellular domain and subsequent release into the cytoplasm. The released intracellular domain then translocates to the nucleus where it interacts with transcription factors and regulates the expression of target genes. This process, known as Notch signaling, is essential for the proper development and function of many tissues and organs.

Applications of Recombinant Human NOTCH4

Recombinant Human NOTCH4 has a wide range of applications in both basic research and clinical settings. Its role in cell signaling and development makes it a valuable tool for studying various biological processes. It has been extensively studied in the fields of embryology, stem cell biology, and cancer research. In addition, recombinant NOTCH4 has been used to investigate the role of Notch signaling in various diseases, including cardiovascular diseases, neurodegenerative disorders, and autoimmune diseases.

Recombinant Human NOTCH4 has also shown potential as a therapeutic target for the treatment of cancer. Aberrant Notch signaling has been linked to the development and progression of many types of cancer, and targeting NOTCH4 specifically may offer a more precise and effective treatment option. In fact, several studies have shown promising results in using recombinant NOTCH4 inhibitors to block tumor growth and induce cancer cell death.

In conclusion, Recombinant Human NOTCH4 is a crucial protein with diverse structural and functional characteristics. Its involvement in cell signaling and development makes it a valuable tool for research and a potential target for therapeutic interventions. With ongoing research and advancements in recombinant protein technology, the potential applications of NOTCH4 continue to expand, offering new insights into the complex mechanisms of cellular processes and potential treatments for various diseases.
