Foldit Puzzles

1299: 85 Residue Monomer Design: No Rebuilding!

This puzzle is similar to recent design puzzles, but we'd like players to avoid using the Rebuild tool. We suspect that the Rebuild tool has been introducing some problematic backbones into Foldit player designs, so the Rebuild tool has been deactivated in this puzzle. In most cases, the Remix tool can be used as an alternative to Rebuild. See the puzzle comments for filter details. The Baker Lab will run folding predictions on your solutions for this puzzle, and those that perform well will be synthesized in the lab. Remember, you can use the Upload for Scientists button for up to 5 designs that you want us to look at, even if they are not the best-scoring solutions!

1298: Revisiting Puzzle 75: Antifreeze Protein

This is a throwback puzzle to the early days of Foldit. This eelpout protein binds nucleated ice crystals to inhibit their growth. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1297: 65 Residue Monomer Design: No Rebuilding!

This puzzle is similar to recent design puzzles, but we'd like players to avoid using the Rebuild tool.

1296: Electron Density Reconstruction 1: Original Density

This is a followup to Puzzle 1249 and Puzzle 1274, this time with a density map drawn directly from the published structure. Players may load in solutions from Puzzle 1249 and Puzzle 1274.

1295: Revisiting Puzzle 74: Platypus Venom

This is a throwback puzzle to the early days of Foldit. This small peptide was discovered in platypus venom—a rare instance of mammalian-produced venom, although this peptide appears similar to more widespread antimicrobials. This protein contains six cysteine residues that oxidize to form three disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1294: 80 Residue Monomer Design: No Rebuilding!

This puzzle is similar to recent design puzzles, but we'd like players to avoid using the Rebuild tool.

1293: Dysferlin C2B Domain: Predicted Contacts

Note: This puzzle was mistakenly posted without a Contact Bonus filter. The puzzle has been closed and reposted as Puzzle 1293b.

1293b: Dysferlin C2B Domain: Predicted Contacts

Note: This puzzle replaces Puzzle 1293, which lacked a Contact Bonus filter. Players may load in solutions from Puzzle 1293.

1292: Revisiting Puzzle 73: Polycystein

This is a throwback puzzle to the early days of Foldit. This domain is a component of a large glycoprotein in humans that has been linked to autosomal dominant polycystic kidney disease. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1291: Dysferlin C2B Domain

This is a domain of the human dysferlin protein. Dysferlin is found in muscle cells and associates with the cell membrane, although its exact function is unknown. Mutations in the dysferlin gene can cause a debilitating type of muscular dystrophy. See the blog for more info. Our collaborators at the Jain Foundation would like to model the structure of dysferlin to better understand its function, and have asked Foldit players to help!
