Companion proteins enhance antibody potency
This week we report the design of new proteins that cluster antibodies into dense particles, rendering them more effective. In laboratory testing, such clustered antibodies neutralize COVID-19 pseudovirus, enhance cell signaling, and promote the growth of T cells more effectively than do free antibodies. This new method for enhancing antibody…

A deep learning approach to protein design
Scientists at the IPD and Ovchinnikov lab at Harvard have applied deep learning to the challenge of protein design, yielding a new way to quickly create protein sequences that fold up as desired. This breakthrough has broad implications for the development of protein-based medicines and vaccines. Computational protein design has…

trRosetta yields structures for every protein family
The field of protein structure prediction has greatly advanced in recent years thanks to increasingly accurate deep-learning methods. A new such method, called trRosetta developed at the Institute for Protein Design, has now made thousands of protein structures available via EMBL-EBI’s Pfam and InterPro data resource. More than 6300 protein structures have been predicted…

Design of transmembrane beta barrels
Biochemists have created barrel-shaped proteins that embed into lipid membranes, expanding the bioengineering toolkit. In a milestone for biomolecular design, a team of scientists has succeeded in creating new proteins that adopt one of the most complex folds known to molecular biology. These designer proteins were shown in the lab…

Dr. Berger awarded WRF translational funding
Washington Research Foundation (WRF) has provided a $250,000 grant to support work carried out by Stephanie Berger, Ph.D., on a new therapeutic for patients with inflammatory bowel disease (IBD). A grant of $50,500 from WRF in 2019 and an award from Washington Entrepreneurial Research Evaluation and Commercialization Hub (WE-REACH) in 2020 enabled Berger,…

New sensors detect coronavirus proteins and antibodies
This week we report [PDF] a new way to detect the virus that causes COVID-19, as well as antibodies against it. Scientists at the Institute for Protein Design have created protein-based sensors that glow when mixed with components of the virus or specific antibodies. This breakthrough could enable faster and more…

Protein patches boost cell signaling
Today we report the design of a new class of protein material that interacts with living cells without being absorbed by them. These large, flat arrays built from multiple protein parts can influence cell signaling by clustering and anchoring cell surface receptors. This breakthrough could have far-reaching implications for stem…

Design of an ultrapotent COVID-19 vaccine candidate
Today we report in Cell (PDF) the design and initial preclinical testing of an innovative nanoparticle vaccine candidate for the pandemic coronavirus. It produces virus-neutralizing antibodies in mice at levels ten-times greater than is seen in people who have recovered from COVID-19. Compared to vaccination with the soluble SARS-CoV-2 Spike protein,…

David Baker awarded 2021 Breakthrough Prize
The Breakthrough Prize Foundation today announced the winners of the 2021 Breakthrough Prize, recognizing an array of achievements in the Life Sciences, Fundamental Physics and Mathematics. The traditional gala award ceremony, attended by superstars of movies, music, sports and tech entrepreneurship, has been postponed until March 2021. David Baker, director…

Antiviral proteins block coronavirus infection in the lab
Today we report in Science [PDF] the design of small proteins that protect cells from SARS-CoV-2, the virus that causes COVID-19. In experiments involving lab-grown human cells, the activity of the lead antiviral candidate produced (LCB1) was found to rival that of the best-known SARS-CoV-2 neutralizing antibodies. LCB1 is currently…
