Description of Recombinant Human TIMM9 Protein, N-His-SUMO

Introduction

Recombinant Human TIMM9 Protein, also known as Translocase of Inner Mitochondrial Membrane 9, is a protein that plays a crucial role in mitochondrial protein import and assembly. It is a member of the TIMM family of proteins, which are involved in the translocation of proteins from the cytosol into the mitochondria. In this article, we will explore the structure, activity, and applications of Recombinant Human TIMM9 Protein.

Structure of Recombinant Human TIMM9 Protein

Recombinant Human TIMM9 Protein is a 10 kDa protein consisting of 91 amino acids. It is composed of a transmembrane domain and a cytoplasmic domain. The transmembrane domain contains two alpha-helices, while the cytoplasmic domain contains a conserved cysteine-rich region. This structure is essential for the function of TIMM9 in protein import and assembly.

Activity of Recombinant Human TIMM9 Protein

The main function of Recombinant Human TIMM9 Protein is to facilitate the import of nuclear-encoded proteins into the mitochondria. It does this by forming a complex with other TIMM family proteins, such as TIMM10 and TIMM12, to create a translocation channel in the mitochondrial inner membrane. This channel allows for the passage of newly synthesized proteins from the cytosol into the mitochondria.

In addition to its role in protein import, Recombinant Human TIMM9 Protein is also involved in the assembly of respiratory chain complexes. It is required for the proper folding and assembly of the cytochrome c oxidase subunit Cox2, which is essential for the function of the respiratory chain. This highlights the importance of TIMM9 in maintaining mitochondrial function and cellular energy production.

Applications of Recombinant Human TIMM9 Protein

Recombinant Human TIMM9 Protein has a wide range of applications in both research and clinical settings. One of its primary uses is in the study of mitochondrial disorders. Mutations in TIMM9 have been linked to several mitochondrial diseases, including deafness, encephalopathy, and Leigh syndrome. Recombinant Human TIMM9 Protein can be used to investigate the role of these mutations in disease development and progression.

Additionally, Recombinant Human TIMM9 Protein has potential therapeutic applications. It has been shown to have a protective effect against oxidative stress-induced cell death in neuronal cells, making it a potential target for neuroprotective therapies. It has also been studied as a potential treatment for cancer, as it has been found to inhibit the growth of tumor cells.

In the field of biotechnology, Recombinant Human TIMM9 Protein is used in the production of recombinant proteins. It is commonly used as a fusion partner for the expression and purification of target proteins, as its small size and stability make it an ideal carrier protein.

Conclusion

In summary, Recombinant Human TIMM9 Protein is a crucial component of the mitochondrial protein import and assembly machinery. Its structure, activity, and applications make it a valuable tool in understanding mitochondrial disorders, developing potential therapies, and producing recombinant proteins. Further research on this protein and its role in cellular function and disease will continue to expand our understanding of its importance in maintaining mitochondrial homeostasis.
