Now, our group has developed a computational method called COMBS that can generate protein sequences from scratch that are able to tightly and specifically bind to challenging targets. COMBS thus enables the rapid generation of proteins that may act as sensors, therapeutics, or delivery vehicles. Aminoacyl tRNA synthetases link amino acids with their cognate tRNAs and are thus critical players in the expansion of the genetic code. However, it has proven incredibly difficult to engineer synthetases to recognize polar, non-natural amino acids that mimic common post-translational modifications (PTMs) of proteins. The ability to precisely program PTMs and monitor their effects on cell fate in disease-relevant mammalian cells has been a longstanding goal.

King created protein subunits that arrange themselves into a virus-like particles (VLPs), displaying viral antigens in regular arrays to elicit an effective immune reaction. Synthetic VLPs offer more opportunities for customization than natural ones, opening up the possibility of vaccines for intractable viruses such as RSV and HIV. King and his colleagues fused the SARS-CoV-2 spike protein to self-assembling nanoparticles and are working on creating the optimal antigen display for a coronavirus vaccine. Silva studied the 3D structure of IL-2 in its high-affinity conformation, the shape it assumes when bound to all three receptor subunits. He built a new protein that emulated that shape but was “otherwise unrelated in topology or amino acid sequence.” It also lacked any binding site for the alpha receptor subunit. By constructing a completely novel protein instead, the team could create a highly stable molecule that bound with high efficiency to the beta and gamma subunits and ignored the alpha subunit.
Designing protein for the masses
Jerry is a graduate student in Harvard’s Molecules, Cells, and Organisms (MCO) program. During his gap year before starting at Harvard, he served the Taiwanese army and then worked with Dan Tawfik at the Weizmann Institute to investigate the origin of peptides and the genetic code in the origin of life. For his PhD, he hopes to elucidate the principles of biomolecular evolution using protein design, evolutionary biology, and high-throughput experimental approaches. When he is not thinking about science, he enjoys cooking, hiking, backpacking, learning languages, and exploring the evolution of human artifacts. Kevin is an undergraduate at Harvard studying computer science and molecular & cellular biology.

Meanwhile, insulin, a hormone produced by the pancreas, helps regulate blood sugar levels by signaling cells to take in glucose from the bloodstream. Raphael's model for evaluating protein structures is posted on bioRxiv as a preprint. The protein system is called LOCKR, for “Latching, Orthogonal Cage/Key Proteins,” and it consists of a six-helix protein that folds into a stable, cage-like formation. The cage can interact with either its own ‘latch’ helix domain, which holds the cage closed, or to another protein—the ‘key’—which triggers a conformational change.
A Beginner’s Guide to the Future of Biology
This press release contains forward-looking statements involving risks and uncertainties, including statements regarding growth and cash flow, and PDL's actual results may differ materially from those in the forward- looking statements. As we continue to unlock the secrets of proteins and learn to harness their potential, the possibilities for protein design are virtually limitless. In this post, we will delve into the basics of protein design, explore its real-world applications, and learn about the interdisciplinary nature of this fascinating field. The synthetic cytokine neoleukin-2/15 was created in an attempt to jettison some very heavy baggage that has dogged cancer researchers for decades. Since the 1980s, the cytokine interleukin (IL)-2 has tantalized oncologists with the promise of harnessing the immune system to attack tumors. IL-2 naturally stimulates T cell proliferation, but it also exerts ferocious side effects on the body, particularly in the lungs.

The precise order of amino acids in a protein chain, like the letters in a word, is crucial. The unique functions of a protein stem from its three-dimensional structure, which is determined by the sequence of amino acids composing the protein. Franzi grew up in Germany and graduated from Albert Ludwigs University Freiburg with a BSc in Molecular Medicine and afterwards a MSc in Biochemistry from University of Leipzig. She pursued her PhD at the Max Planck Institute for Terrestrial Microbiology where she worked with Dr. Georg Hochberg in the area of Evolutionary Biochemistry. In her work she investigated self-assembly of proteins and the evolution of biological complexity.
The world of proteins is incredibly complex, offering endless possibilities for exploration and discovery. They are found inside every living thing and act as structural components, transporters, signaling molecules, and much more.

We believe that Artificial Intelligence is starting a revolution in this field, and it will radically change it forever. The exquisite functions of naturally occurring proteins solve the challenges faced during evolution. However, we face challenges today that were not faced during natural evolution. The goal of the Institute for Protein Design (IPD) is to develop and apply methods for designing a whole new world of synthetic proteins to address these challenges.

In addition to predicting protein structures, computational methods also allow scientists to simulate how proteins will interact with other molecules. This information is vital in refining protein designs to optimize their stability, binding affinity, or catalytic activity. Now, without human intervention, a generative AI is able to develop drug molecules from scratch that match a protein structure. This groundbreaking new process ensures right from the start that the molecules can be chemically synthesised.
During undergrad, she worked on molecular immunology at JHU and machine learning for protein engineering at Microsoft Research. Jody is working on de novo design of ligand-binding proteins using computational and deep learning approaches. Our lab invents and uses synthetic biology tools and approaches to build tissues in the lab. Over the past 16 years, UW researchers have made significant progress in protein design and protein structure prediction, developing the world leading Rosetta software. Over this period, UW scientists have developed methods for designing proteins with a wide range of new functions, including catalysts for chemical reactions, HIV and RSV vaccine candidates, and flu virus inhibitors. The IPD integrates these strengths in protein design with Seattle-area expertise in biochemistry, engineering, computer science and medicine, and leverages the exceptional Seattle strength in the software industry.
On another level, the mission of the lab is training the next generation of scientists and leaders in the field of regenerative medicine. The lab is committed to generating the best work environment to make the best science possible, and to foster multidisciplinary research using expertise from engineering, developmental biology, medical science and computer science. Besides, they catalyze rapid chemical reactions in mild conditions such as standard pressure and non-toxic solvents. With such attractive properties, it is no wonder Biochemists and Chemists have dreamed of designing proteins with customizable properties for decades.
