Накратко на български

Биологичните нанопори се изследват като средство за разчитане на последователността от протеини в една единствена молекула. Това ще помогне да се разбере точно кои протеини присъстват в една клетка във всеки един момент.

Single molecule protein sequencing using biological nanopores

Biology (and science as a whole) is continually driven forward by advances in experimental technology. Microscopes capable of observing the previously unobservable, analytical techniques allowing us to isolate and study different substances, sequencers providing direct access to the DNA code of life: these developments pave the way to medical, engineering, and scientific discoveries of great importance. Proteomics remains a relatively dark area in biology, due to the lack of any experimental tool for characterizing samples of protein as small or as heterogeneous as a single cell. The current gold standard in protein identification and sequencing, mass spectrometry, is presently incapable of this task. A tool capable of identifying or sequencing proteins at the single-molecule level would provide us with the capability to answer the seemingly simple yet currently unapproachable question of what, exactly, is floating around in a cell at any given time. This project's goal was to perform proof-of-principle experiments on a concept for such a technology, based on nanopore sequencing. Nanopore sequencing has additional advantages, as a highly accessible tool with minimal overhead cost and a high degree of engineerability, and as a technology whose core elements are already industrially produced and commercialized. Overall, our hope is to develop a robust single-molecule protein sequencing technology that is broadly accessible to scientists and clinicians.

Цел на проекта

Despite the importance of post-translational variation to the function of proteins in a living organism, sequencing proteins to study these variations is still a costly and time-consuming process, with intrinsic limitations. Protein sequencing and detection of post-translational modifications (PTMs) by mass spectrometry, the current gold standard, requires extensive sample preparation and large sample sizes, and possesses a limited dynamic range with respect to sample concentration. These limitations severely restrict its application to biological and clinical problems. A robust method for sequencing proteins and detecting PTMs at the single-molecule level would be revolutionary for proteomics research, allowing biologists to quantify low-abundance proteins as well as distributions and correlations of PTM patterns, all at a single-cell level. I propose a first-of-kind method for protein sequencing with applications in fundamental biology, cancer immunotherapy, and pharmaceutical development. This method uses biological nanopores in a manner similar to nanopore DNA sequencing, an established single-molecule sequencing technology capable of high throughput and single-molecule sensitivity. Developing this method for protein sequencing comes with many significant challenges, which will be addressed over the course of the proposed research.
