Anti-inflammatory designs queued for testing!

We've selected 100 of the most promising designs from Puzzle 1824 and Puzzle 1828, which will be synthesized and tested for binding to the IL-6 receptor (IL6R).

In our last blog post, we announced a similar experiment for binders to the coronavirus spike protein. (We had some issues getting the necessary materials for that experiment, but we've come up with a workaround and that experiment is back on track!) These latest designs will be tested using the same kind of experiment, using yeast display and flow cytometry techniques, but swapping in the IL6R target instead of spike protein. See our previous YouTube video for more.

IL6R is a protein found on human immune cells, and plays a role in the "cytokine storm" that can cause dangerous inflammation in severe cases of COVID-19. A protein that binds to IL6R might be useful as a drug to temper this inflammation. We'll be testing these 100 Foldit player-designed proteins to see if they bind to the IL6R in a controlled lab setting. It will be several weeks before the experiment results come in, but we'll continue running more anti-inflammatory puzzles to try and develop even better designs.

Below are the 100 selected designs (click for full-size image). Remember to fill out our username sharing form if you want to see your username in Foldit updates!

how you can select so many "promizing" designs and test them in lab !

feeling like that year or two on monomers was worth it!

after we spent so long on monomers, dimers, trimers and more it is really cool to see them working in an applied fashion. And neat to see some non-traditional folds working too.

We'd all love feedback. I'm wondering how many sidechain bonds are enough versus shape conformancy. I'm personally better at the latter, but would like to know where I could improve

Thanks for all the hard work at the lab...

Hmm, it's working okay for me. Can say more about what isn't working? Are you able to load the Google form, or are you unable to submit your responses? What browser are you using?

I think it was my internet connection. The link was not loading, but a few hours later it worked. Thanks for reply!

We're sorry about the extra step, but we like to be careful about identifying the work of individual Foldit players. Lots of players have clearly expressed a preference for privacy.

Thank you for filling out the form! I've updated the post.

Testing good , but not to test on cov19 protein spike?

Well finally team started to work on testing some protein designs, still why noone from USA clinics with covid19 patients can provide samples with actual covid19 protein spikes?
I repeat in Germany we have lots and lots of organizations maybe we can arrange something there?

I like how mine is the goofiest one. Why do we all end up doing 3 or 4 helixes? Maybe encourage anything but those shapes because they don't seem to represent much variety.

helixes rule

Helixes or helices get a lot of atoms in a small space as compared to sheets or loops. Triple helixes seem to work better than quadruple helixes for complex numerological reasons that escape me.

As far as orthography goes, I've been leaning toward "helixes" since we're using English and not ancient Greek. But I just realized I'm comfortable saying the plural of "matrix" is "matrices" and not "matrixes. So much for consistency.

Doesn't that bug you a bit?

Doesn't that bug you a bit? It feels like it leaves the creativity out if everything ends up being 3/4 helices. At that point it would just be a matter of a recipe to create a 3 helix shape, move them into position, and try every rotation until you get the highest score.

... or buries the most whatevers.

I've been obsessed with playing with this app for the past few months. It feels like I have a few shapes I play around with but I don't know how they play out.

It would be nice to be able to submit a few shapes for each round rather than "this is my highest scoring shape." Because I may try to see how a few different designs look and shake out.

You can share 5 solutions with Scientists
You can explicitly put many different solutions
on the Foldit server. I think the limits right
now are 10 for yourself, 10 for your group, and
5 for the scientists. Foldit also automatically
sends your latest solutions to the server 
periodically when you are playing online. This
lets the site keep track of your top solo and
evolver scores. I have been told that at the
end of each puzzle, the scientists look at
your best solo and evolver solutions plus
the 5 solutions you shared with scientists.
I think they also use many of the solutions 
automatically saved to the server in plots
