TMT Proteomics | 6 Important Points

1. Introduction: What is TMT proteomics?

TMT proteomics is a unique field of investigation that explores the three-dimensional structure of a protein. The technique utilizes the unique attributes of light-based microscopy (laser) to scan through high-resolution images, enabling researchers to observe and manipulate the protein’s activities and interactions with other proteins. TMT proteomics is unique because it offers a complementary approach to traditional structural biology methods while providing researchers with a powerful new tool for functional genomics research.

TMT proteomics offers researchers a means to investigate unprecedented levels of detail within a single protein, including the shared and distinct yet particular functions of thousands or millions of proteins. Researchers use these methods to study many aspects of biology and behavior, including cancer and neurodegenerative diseases such as Alzheimer’s disease and amyotrophic lateral sclerosis (ALS). TMT proteomics could ultimately advance research in molecular pathology, cell biology, molecular engineering, human health and wellness, and human diseases such as Alzheimer’s.

2. What are the benefits of TMT proteomics?

TMT proteomics is a term used to describe the combined use of computational, experimental, and clinical methods to elucidate the molecular mechanisms by which viral infections alter host cell function.

TMT proteomics was first introduced in the field of infectious disease in 2009, with a paper examining the role of the FcγR2 cytokine receptor in HIV infection. The authors found that HIV infects cells by increasing IL-10 production and promoting apoptosis, a process known as cell death, by activating FcγR2—a receptor involved in innate immunity expressed on many types of immune cells (e.g., T cells) and macrophages.

3. What are the applications of TMT proteomics?

If you’re a seasoned professional in Proteomics, then you know that TMT proteomics is a multi-disciplinary field. It involves a lot more than sequencing the proteome. It’s about understanding the structure and function of the proteins that make up our cells. But it’s also about answering questions such as “What is happening in one protein or cell from one person?” or “What are the protein interactions between one gene or gene family in one person?”
It’s not as easy to learn about Proteomics as it sounds. Numerous disciplines are involved in TMT proteomics, and each has a vocabulary for describing how the results are obtained.

The first item we must do is define what we mean by “proteome.” Francis Crick coined the term, and he explained it this way:Every protein molecule has an identity known only to itself but can be identified by its location within a population of molecules called a proteome.

4. How does TMT proteomics work?

The subject of TMT proteomics has been discussed for quite a while now. One interesting thing is that there are different types of TMT proteomics, and each class can be used in other parts of the cell.

Theoretically, these should help you make an educated selection of your study targets specific proteins. For example, when using TMT proteomics to study a particular protein, you would be able to know which specific protein is being targeted by your experiment. By correlating your results with the known function of the protein, you may be able to improve upon your research.

But there are also some drawbacks regarding using TMT proteomics on specific proteins. For example, some proteins are known not to have any special functions in humans but can still be regulated (as seen in the case of IGF-1). There’s also the issue that not all proteins interact with other proteins to function normally (i.e., IGF-1 interacts with IGF-2).

TMT proteomics relies on the fact that every protein interacts with every other protein at one point or another in its lifetime. So instead of focusing on a single protein for an entire lifetime, researchers can focus on a particular part of its life cycle (e.g., transcriptional activity), thereby reducing their number of choices from thousands to hundreds.

Furthermore, they can go as far as looking at only one gene at a time – similar to what you would do when looking at a single gene (e.g., IGF-1) – so they’re less likely to miss essential interactions between genes or miss many gene interactions altogether due to differences in expression levels or expressions over time (which could contribute towards differential regulation states) between different tissues. Theoretically, this should lead to better results than working with just one tissue type, such as liver cells. Still, it will take time and further investigation before we can make any accurate conclusions here.

5. What are the limitations of TMT proteomics?

TMT proteomics is an exciting new way to analyze protein tissue from a living organism. With this approach, a living cell can be analyzed for its unique chemical and physical properties, guiding to a better arrangement of the function and regulation of its various systems.

The name TMT proteomics is chosen with purpose: researchers have long known that the most extensive library of proteins exists in the human body, but they are still poorly understood due to their low structural resolution. Now, we can begin to make sense of this information by probing tissues with molecular probes that allow us to measure specific structures at a much more satisfactory resolution than was previously possible. Studying these proteins will lead us to a deeper understanding of metabolic physiology and potentially improve our treatments for diseases such as Alzheimer’s, cancer, diabetes, and others.

6. Conclusion: The future of TMT proteomics

TMT proteomics is a relatively new field that is growing in popularity. TMT (trans-molecular) methods are used to analyze proteins and explore the structure of cellular systems. This section aims to introduce readers to TMT proteomics, its current applications, and future research.
