Description of Recombinant Human CHGA Protein, N-His

Introduction to Recombinant Human CHGA Protein

Recombinant Human CHGA Protein, also known as Chromogranin A (CHGA), is a protein that is produced through genetic engineering techniques. This protein is encoded by the CHGA gene and is primarily found in secretory granules of neuroendocrine cells. It is involved in the storage and transport of hormones and neuropeptides, making it an essential component in the regulation of various physiological processes.

Structure of Recombinant Human CHGA Protein

The structure of Recombinant Human CHGA Protein is composed of 439 amino acids and has a molecular weight of approximately 48 kDa. It is a highly conserved protein, with a sequence similarity of 98% between humans and other mammalian species. The primary structure of CHGA consists of a signal peptide, a propeptide, and a mature peptide. The signal peptide is responsible for directing the protein to the secretory pathway, while the propeptide is involved in the processing and packaging of the mature peptide.

The mature peptide of CHGA contains several functional domains, including the acidic region, the basic region, and the cleavage site. The acidic region is rich in negatively charged amino acids and is responsible for the pH-dependent solubility of the protein. The basic region, on the other hand, contains several positively charged amino acids and is involved in the binding of calcium ions. The cleavage site is where the propeptide is removed, resulting in the formation of the mature CHGA protein.

Activity of Recombinant Human CHGA Protein

The primary function of Recombinant Human CHGA Protein is the storage and transport of hormones and neuropeptides. It is primarily found in neuroendocrine cells, which are specialized cells that produce and release hormones and neurotransmitters. CHGA is involved in the packaging of these molecules into secretory granules, which are then transported to their respective target tissues.

In addition to its role in hormone and neuropeptide storage, CHGA has also been found to have antimicrobial properties. It can inhibit the growth of bacteria, fungi, and viruses, making it an important component of the body’s immune system. CHGA achieves this by binding to the cell membranes of these microorganisms and disrupting their integrity, ultimately leading to their death.

Application of Recombinant Human CHGA Protein

Recombinant Human CHGA Protein has a wide range of applications in the fields of medicine and biotechnology. One of its primary uses is in the diagnosis and monitoring of neuroendocrine tumors. CHGA levels in the blood have been found to be elevated in patients with these types of tumors, making it a useful biomarker for their detection and management.

Another important application of CHGA is in the development of new antimicrobial agents. Its ability to inhibit the growth of microorganisms has led to the development of CHGA-based drugs that can potentially be used to treat various infections. This is especially important in the face of the growing problem of antibiotic resistance.

Furthermore, Recombinant Human CHGA Protein has also been studied for its potential in the treatment of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. It has been found to have neuroprotective properties, which could potentially slow down the progression of these diseases.

Conclusion

In summary, Recombinant Human CHGA Protein is a versatile and important protein that plays a crucial role in the regulation of various physiological processes. Its unique structure and diverse functions make it a valuable tool in the fields of medicine and biotechnology. With ongoing research and advancements in genetic engineering techniques, the potential applications of CHGA are constantly expanding, making it an exciting area of study in the scientific community.
