What if scientists could design a completely new protein that is precision-tuned to bind and inhibit cancer-causing proteins in the body? Collaborating scientists at the UW Institute for Protein Design (IPD) and Molecular Engineering and Sciences Institute (MolES) have made this idea a reality with the designed protein BINDI. BINDI (BHRF1-INhibiting Design acting Intracellularly) is a completely novel protein, based on a new protein scaffold not found in nature, and designed to bind BHRF1, a protein encoded by the Epstein-Barr virus (EBV) which is responsible for disregulating cell growth towards a cancerous state.

A new paper is out in the June 5 issue of Nature entitled Accurate design of co-assembling multi-component protein nanomaterials. Scientists at the Institute for Protein Design (IPD), in collaboration with researchers at UCLA and HHMI, have built upon their previous work constructing single-component protein nanocages and can now design and build self-assembling protein nanomaterials made up of multiple components with near atomic-level accuracy. Learn more about this innovative work at this link.
May was a busy month at the IPD, with some new publications and exciting announcements! Learn more here.
In a recent PNAS paper entitled “Removing T-cell epitopes with computational protein design”, IPD researchers combine machine learning with computational protein design to demonstrate immune silencing of protein targets. This deimmunization has the potential to reduce or eliminate immunogenicity of protein therapeutics. Learn more at this link.
A recent Nature issue exposed the dismaying fact that many women are deterred from pursuing a career in science, especially at the highest levels (postdoctoral positions, faculty position, scientific advisory boards to start up companies, etc). To talk about this significant gender gap in science and the issues female scientists face, Baker lab members participated in an informal lunch discussion to determine what specific steps could be taken as a group to encourage and promote women within our own scientific community.

With a very generous $8 M gift from the Washington Research Foundation (WRF), the IPD has launched the WRF-IPD Innovation Fellows Program supporting research partnerships between the IPD and other Seattle-area research institutes or UW departments. We are recruiting exceptionally talented researchers who have just finished their PhD to join expert laboratories at local institutions where they will apply protein design methods to current health, energy, and materials related research problems. For more information see our web page here.
The “Three Dreamers” are a group of Seattle-based philanthropists whose family members are suffering from Alzheimer’s disease (AD). The IPD has partnered with the Three Dreamers, the Foldit community and AD researchers at the UW to design new proteins targeting amyloid, thought to be the cause of AD. Learn more at this link.
Re/Code writer James Temple has written an interesting article on David Baker’s efforts to design a new world of proteins. The article covers the IPD efforts to design proteins that neutralize the flu virus, Alzheimer’s disease amyloid protein, and how the IPD is engaging citizen scientists in the Rosetta@home and Foldit projects.

Baker lab members published in Nature Chemical Biology a paper entitled “Design of activated serine-containing catalytic triads with atomic-level accuracy“, describing the computational design of proteins with idealized serine-containing catalytic triads which can capture and neutralize organophosphate probes. This work has utility in design of scavengers of environmental toxins. Learn more at this link.

What if scientists could design proteins to capture specific metals from our environment? The utility for cleaning up metals from waste water, soils, and our bodies could be tremendous. Dr. Jeremy Mills and collaborators in Dr. Baker’s group at the University of Washington’s Institute for Protein Design (IPD) address this challenge in the first reported use of computational protein design software, Rosetta, to engineer a new metal binding protein (“MB-07”) which incorporates an “unnatural amino acid” (UAA) to achieve very high affinity binding to metal cations.

In a widely cited Nature paper entitled Proof of principle for epitope-focused vaccine design, IPD researchers and collaborators invented a new method to design novel proteins for use as a candidate vaccines to protect against respiratory syncytial virus (RSV), a significant cause of infant mortality.

The Seattle Health Innovators recently visited the Institute for Protein Design, and wrote a nice blog entitled “Crowdsourcing the design of new molecules to improve healthcare and the environment.” The article provides a nice look into the Institute for Protein Design. Learn more at this link.
Purification of antibody IgG from crude serum or culture medium is required for virtually all research, diagnostic, and therapeutic antibody applications. Researchers at the Institute for Protein Design (IPD) have used computational methods to design a new protein (called “Fc-Binder”) that is programed to bind to the constant portion of IgG (aka “Fc” region) at basic pH (8.0) but to release the IgG at slightly acidic pH (5.5). Published on-line at PNAS (Dec. 31, 2013), the paper is entitled Computational design of a pH-sensitive IgG binding protein, co-authored by Strauch, E. – M., Fleishman S. J., & Baker D.

Dr. Ingrid Swanson Pultz, a Translational Investigator at the Institute for Protein Design won first prize at the UW Center for Commercialization 2013 Innovator Recognition Event, for KumaMax, an enzyme designed in the Baker lab to efficiently break down gluten within the acidic environment of the stomach, before it can reach the small intestine where intact gluten may otherwise cause an inflammatory reaction in people who suffer from celiac disease.

V-type nerve agents are among the most toxic compounds known, and are chemically related to pesticides widespread in the environment. Using an integrated approach, described in an ACS Chemical Biology paper entitled Engineering V-type nerve agents detoxifying enzymes using computationally focused libraries, Dr. Izhack Cherny, Dr. Per Greisen, and collaborators increased the rate of nerve agent detoxification by the enzyme phosphotriesterase (PTE) by 5000-fold by redesigning the active site.

Dr. Paul Ramsey, CEO of UW Medicine, announces the establishment of the Institute for Protein Design (IPD). “A major challenge for designing proteins for specific purposes is predicting three-dimensional shape from the amino acid sequence. Dr. David Baker, UW professor of biochemistry and an investigator of the Howard Hughes Medical Institute, has had remarkable success in making these predictions and in designing new proteins with new functions.”
Baker will serve as the director or the IPD which will coalesce and expand existing strengths within the UW and Seattle. The IPD will integrate UW expertise in biochemistry, engineering, computer science and medicine, and leverage local strength in the software industry to design a whole new world of synthetic proteins that address challenges in medicine, energy and technology.
