Note: This puzzle was closed early, due to an error in the puzzle setup that allowed free movement of the IL-7R binding helices. The puzzle has been reposted as Puzzle 1723b.

This symmetric design puzzle has C3 symmetry, with three symmetric chains. This puzzle is a little different from other symmetry puzzles, in that we want players to focus on building a smaller interface between the chains. The "Core Limit: Complex" objective will incur penalties if there are too many buried residues in the total assembly. See the puzzle comments for Objective 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!

Design a protein that binds IL-7R!

This is a throwback puzzle to the early days of Foldit. This DNA-binding domain is part of a bacterial integrase protein, which facilitates the insertion of new DNA into the bacterial chromosome. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

Design a protein that binds IL-7R!

This symmetric design puzzle has C2 symmetry, with two symmetric chains. No more than 50% of residues may form helices, and all loops must match one of the Ideal Loop Building Blocks found in the Blueprint tool. We've omitted the "Core Exists: Complex" objective to simplify the puzzle, but we still expect that designs with a strong hydrophobic interface (orange sidechains) will score best. See the puzzle comments for Objective 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.

Design a protein that binds IL-7R!

This is a throwback puzzle to the early days of Foldit. This protein helps to transfer electrons between substrates in bacteria. The protein is modeled here in reducing conditions, and no disulfides are expected to form. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.
