Foldit Puzzles
Play puzzles to help scientific research and compete with other players. New puzzles are posted every week.

This is a throwback puzzle to the early days of Foldit. This small domain is part of a larger protein found at high concentrations of the lens of the eye; historically, this protein was purified from the eyes of B. taurus for research. The protein is modeled here in reduced state, so 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.

Design a small molecule which can bind VHL! This is the third in a series of puzzles using the small molecule design tools to design small molecule binders to the von Hippel-Lindau E3 ubiquitin ligase. We don't want you to modify the protein, but instead we'd like you to build new small molecules which fit into the VHL pocket. See the new "Inside the Pocket" and "Fun with Fragments!" tutorials to learn how to use the small molecule design tools.

Design a protein that can bind to the TGF-beta receptor! This puzzle enables AlphaFold predictions for your designed binder. Once you've designed a binder for the target, upload your solution for AlphaFold using the AlphaFold prediction tool. AlphaFold will predict the structure of your binder chain only (i.e. in the unbound state, in the absence of the target). If you load this prediction, then Foldit will attempt to align the prediction with your solution (i.e. in the bound state, making an interface with the target). If you continue working off of the AlphaFold prediction, you may need to make adjustments at the interface where the binder interacts with the target.

We previously gave you 5 server predictions to solve the structure of the human astrovirus (HAstV) capsid protein. This time we are providing you with 1 prediction from the HHpred server to work with. Good luck!

Design a symmetric protein trimer, with 3 identical chains of 90 residues each! This puzzle enables AlphaFold predictions for the monomer subunit of your design, so you can upload your solution for AlphaFold using the AlphaFold prediction tool. AlphaFold will predict the structure of your monomer subunit only (i.e. in the unbound state, in the absence of other symmetric copies). If you load this prediction, then Foldit will attempt to align the prediction with your solution. If you continue working off of the AlphaFold prediction, you may need to make adjustments at the interface where the monomer subunit interacts with symmetric copies.

Design a protein that can bind to CD47! This puzzle enables AlphaFold predictions for your designed binder. Once you've designed a binder for the target, upload your solution for AlphaFold using the AlphaFold prediction tool. AlphaFold will predict the structure of your binder chain only (i.e. in the unbound state, in the absence of the target). If you load this prediction, then Foldit will attempt to align the prediction with your solution (i.e. in the bound state, making an interface with the target). If you continue working off of the AlphaFold prediction, you may need to make adjustments at the interface where the binder interacts with the target.

This is a throwback puzzle to the early days of Foldit. This protein is secreted at the site of inflammation, recruiting monocytes and T cells to help fight an infection. This protein contains four cysteine residues that oxidize to form two disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

This sandbox puzzle features a binder design by nspc in Puzzle 2043: CD47 Binder Design. This design makes excellent hydrophobic contacts with the CD47 target and does a good job of satisfying buried polar atoms with H-bonds. For more, check out Foldit Lab Report #25 on YouTube! This sandbox puzzle is non-competitive and will not award any points.

Design a symmetric protein trimer, with 3 identical chains that assemble together! This puzzle enables AlphaFold predictions for the monomer subunit of your design, so you can upload your solution for AlphaFold using the AlphaFold prediction tool. AlphaFold will predict the structure of your monomer subunit only (i.e. in the unbound state, in the absence of other symmetric copies). If you load this prediction, then Foldit will attempt to align the prediction with your solution. If you continue working off of the AlphaFold prediction, you may need to make adjustments at the interface where the monomer subunit interacts with symmetric copies.
