Recombinant Human MRPS25 Protein, N-His-SUMO

Introduction to Recombinant Human MRPS25 Protein

Recombinant Human MRPS25 Protein, also known as Mitochondrial Ribosomal Protein S25, is a protein that is encoded by the MRPS25 gene in humans. It is a component of the small subunit of the mitochondrial ribosome and plays a crucial role in protein synthesis within the mitochondria. In this article, we will delve deeper into the structure, activity, and applications of this important recombinant protein.

Structure of Recombinant Human MRPS25 Protein

The MRPS25 gene is located on chromosome 1 and is composed of 6 exons that span over 11 kilobases. The protein itself is composed of 103 amino acids with a molecular weight of 11.8 kDa. It is a highly conserved protein, with identical or similar sequences found in various species such as mice, rats, and zebrafish.

The crystal structure of Recombinant Human MRPS25 Protein has been determined, revealing its unique 3-dimensional shape. It consists of two domains, the N-terminal domain and the C-terminal domain, connected by a flexible linker region. The N-terminal domain is responsible for binding to the small subunit of the mitochondrial ribosome, while the C-terminal domain is involved in the recruitment of aminoacyl-tRNA during protein synthesis.

Activity of Recombinant Human MRPS25 Protein

Recombinant Human MRPS25 Protein is a crucial component of the small subunit of the mitochondrial ribosome, which is responsible for translating the genetic code into proteins within the mitochondria. It specifically binds to the 12S rRNA, a component of the small subunit, and helps in its proper folding and stabilization.

Furthermore, Recombinant Human MRPS25 Protein is involved in the recruitment of aminoacyl-tRNA during protein synthesis. It interacts with the mitochondrial translation elongation factor EF-Tu, which is responsible for delivering the correct aminoacyl-tRNA to the ribosome. This interaction is essential for the proper functioning of the mitochondrial ribosome and efficient protein synthesis.

Applications of Recombinant Human MRPS25 Protein

Recombinant Human MRPS25 Protein has several applications in both research and clinical settings. It is commonly used as an antigen in studies aimed at understanding the role of mitochondrial ribosomal proteins in various diseases. For example, mutations in MRPS25 have been linked to mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome, a rare genetic disorder affecting the brain and muscles.

Additionally, Recombinant Human MRPS25 Protein has been used in studies investigating the role of mitochondrial ribosomal proteins in cancer. It has been found to be overexpressed in certain types of cancer, such as hepatocellular carcinoma, and may play a role in tumor growth and progression. It is also being studied as a potential therapeutic target for cancer treatment.

In clinical settings, Recombinant Human MRPS25 Protein can be used as a diagnostic tool for MELAS syndrome. Detection of mutations in the MRPS25 gene can aid in the diagnosis of this rare disorder, which can be difficult to diagnose based on symptoms alone.

Conclusion

In summary, Recombinant Human MRPS25 Protein is an essential component of the small subunit of the mitochondrial ribosome, involved in protein synthesis within the mitochondria. Its unique structure and activity make it an important protein in various research and clinical applications. Further studies on this protein may provide valuable insights into the role of mitochondrial ribosomal proteins in various diseases and their potential as therapeutic targets.
