This is a throwback puzzle to the early days of Foldit. This particular protein is known as ubiquitin, and plays a prominent role in the protein degradation pathway. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been and to provide newer players with puzzles that are still scientifically relevant.

This is a follow-up to Puzzle 1823, but players noticed that the first 15 amino acids are highly predicted to be a signal peptide, so we have trimmed those residues from this puzzle. This protein is encoded in the viral genome of SARS-CoV-2, but the protein's structure is still unknown. If we knew how this protein folds, we might be able to figure out its exact function. Refold this different starting model to find higher-scoring solutions, which will tell us how this protein is most likely to fold!

Design a binder against coronavirus! We're challenging players to design an antiviral protein that could bind to the 2019 coronavirus spike protein and disrupt viral infection. The starting structure is a solution designed by Susume in our previous Round 3 puzzle. This solution makes an excellent interface with the target, but we're concerned that the binder may not fold properly, especially the loops connecting the three helices. We're asking Foldit players to try and improve this design so that it folds up correctly and can bind to the target! Players also have freedom to redesign an entirely new solution from scratch.

Design an anti-inflammatory protein for COVID-19! Many COVID-19 complications are caused indirectly by the virus, and result from a severe over-stimulation of the human immune system. This kind of immune over-stimulation is commonly called a "cytokine storm." During a viral infection, immune cells normally release signaling proteins called cytokines, which inform the rest of the immune system about the infection and trigger inflammation. The inflammation is supposed to help the immune system fight off the infection, but too much inflammation can result in sepsis and organ failure.

This is a follow-up to Puzzle 1820, but this time we are providing you with a starting model. Players may load in previous work from Puzzle 1820. This protein is encoded in the viral genome of SARS-CoV-2, but the protein's structure is still unknown. If we knew how this protein folds, we might be able to figure out its exact function. Refold this starting model to find higher-scoring solutions, which will tell us how this protein is most likely to fold!

This is a throwback puzzle to the early days of Foldit. This protein is found in the nucleus of stem cells in mice, and is important for maintaining the pluripotency of the stem cell. The protein is modeled here as in a reduced environment, so no disulfide bonds are expected to form. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been and to provide newer players with puzzles that are still scientifically relevant.

Design a binder against coronavirus! We're challenging players to design an antiviral protein that could bind to the 2019 coronavirus spike protein and disrupt viral infection. The starting structure is a solution designed by Steven Pletsch in our previous Round 3 puzzle. This solution makes an excellent interface with the target, but we're concerned that the binder may not fold properly, especially the loops connecting the three helices. We're asking Foldit players to try and improve this design so that it folds up correctly and can bind to the target! Players also have freedom to redesign an entirely new solution from scratch.

Fold this coronavirus protein! This protein is encoded in the viral genome of SARS-CoV-2, in a region called ORF8, but the protein's structure is still unknown. Evidence suggests this protein triggers a stress signal in the infected cell. If we knew how this protein folds, we might be able to figure out its exact function. The puzzle's starting structure shows SS predictions from PSIPRED, and hints which parts of the protein might fold into helices or sheets. Refold this protein to find high-scoring solutions, which will tell us how this protein is most likely to fold!

This is a throwback puzzle to the early days of Foldit. This is a portion of a troponin protein found in the skeletal muscle of turkeys. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been and to provide newer players with puzzles that are still scientifically relevant.

Design a binder against coronavirus! We're challenging players to design an antiviral protein that could bind to the 2019 coronavirus spike protein and disrupt viral infection. The starting structure is a solution designed by spvincent in our previous Round 2 puzzle. This solution makes an excellent interface with the target, but we're concerned that the binder may not fold properly. Our predictions suggest that the two sheets in this solution will not fold up as designed. We're asking Foldit players to try and improve this design so that it folds up correctly and can bind to the target! Players also have freedom to redesign an entirely new solution from scratch.
