RFD4 Proteina How IPD Researchers and NVIDIA Design New Proteins with AI

Proteins in nature solve all the problems that arose during evolution. They digest our food, they mediate the currents going through our brain when we think, they power our motion. They're almost like magical things and the promise of being able to design new proteins is that we can now solve these problems that weren't relevant during evolution but are really important for humans today. These are challenges nature never faced, things that nature never had the time or chance to develop against, such as degrading man-made pesticides, curing Alzheimer's disease, finding this new cancer target, fixing nitrogen in a more environmentally friendly way. This project began about a year ago with a very small group of researchers from both NVIDIA Research and the Baker Lab here at the University of Washington The collaboration with NVIDIA has been great in fundamental level algorithm optimization, the incredible expertise. It showed me what kind of innovation is possible at the right place and the right time with the right resources. RFdiffusion 4 Protea unites concepts from the RF Diffusion series of models with concepts from the Protea Complex series of models developed at NVIDIA to make something that's more powerful than any previous model. When we first saw the results of the computer, we couldn't believe them. They were actually too good to be true. We wanted to put the model to a real test. It takes so long to go from that idea or proof of concept to like a vial of a drug that can be injected into a patient. It's like a 10 to 12 year process and it's like a billion dollars in between. With the introduction of RFdiffusion 4 Protea, we see these molecules that we can take directly off the computer and not only do they bind to the target that we intend, there's this ten to a thousand fold increase in the tightness with which these designs are binding. It's an incredible advancement in terms of using these computational tools to speed up the process of drug design. I work on making enzymes that break down pesticides. Enzymes are great because they do very selective chemistry, so ultimately it's cleaner for the world. I've been working on this problem for a year. With the new model, RFdiffusion 4 Protea, we did it in just four days. And not only that, but the best one that we found was over a thousand times better than the previous enzymes I had developed over the past year. The way chemistry is done is going to be changed forever. I'm very excited to see all the great things that people do with RFD4 Protea and how it makes the world a better place.
