Happy (but mostly relieved) to share my dream project with @boudkerlab.bsky.social, now published in @natsmb.nature.com! We used evolution, protein engineering & cryoEM to uncover how ion coupling in glutamate transporters works, and how it evolved.🧵

Evolutionary analysis reveals the origin of sodium coupling in glutamate transporters - Nature Structural & Molecular Biology

Reddy et al. used ancestral protein reconstruction, cryo-electron microscopy and functional assays to elucidate how a secondary active transporter evolved to harness the energy of sodium gradients to ...

Yes, I think I agree. There are two problems: 1) the approach they use isn’t very accurate even for natural proteins and 2) any model will behave very differently for sequences close to the training set than for those far away, so their result is expected just from how the model is trained

Sam Berry @sberry.bsky.social · Sep 1

To my knowledge there is no evidence that that networks like ESMFold accurately predict structural perturbations upon mutation? So yeah seems it’s entirely analysis *of the model* not of actual protein biophysics

RFK Jr. is not a vaccine skeptic. He's a vaccine denier whose anti-science extremist views and actions are destroying one of humanity's greatest scientific achievements. He's going to kill a lot of people, and those deaths are on the 52 Republican senators who confirmed him and those enabling him.

This is a very cool ancestral reconstruction study by @krishnareddy.bsky.social et al. that I recommend reading! @rachellegaudet.bsky.social and I thought it was so interesting that we wrote a News & Views about it, check it out: rdcu.be/eCfyl

As a note - AlphaFold and other similar algorithms can still do reasonably well without MSA info. They really have learned principles from the PDB (but these principles are NOT physical protein folding - as evidenced by that they can’t predict destabilizing muts etc)

Do you think it would be be more reasonable to benchmark these kinds of models against raw NMR data (e.g. by simulating NMR data from the predicted ensemble, if that’s possible) or are there still too many sources of variability going into the raw data?

I think it says everything here that the locked-away industry version of AlphaFold3 they want to build is based on... OpenFold, which was developed to be open-source by academics. Industry is built on the advances of open-source research.

www.nature.com/articles/d41...

AlphaFold is running out of data — so drug firms are building their own version

Thousands of 3D protein structures locked up in big-pharma vaults will be used to create a new AI tool that won’t be open to academics.

"On October 8, 1931, a law went into effect requiring every Italian university professor to sign an oath pledging their loyalty to the government of Benito Mussolini. Out of over 1,200 professors in the country, only 12 refused. All of them were immediately fired." www.chronicle.com/article/what...

Publishing this *now* is so embarrassingly tone-deaf and anti-science I almost can’t believe it - just as this exact ideology is being used in a fascist takeover of the US and the accompanying wholesale attack on science and free speech

Hemant Mehta @friendlyatheist.com · Feb 27

Lol. All the anti-trans, reflexively contrarian, “anti-woke” scientists have contributed to a book about how science is under attack.

Somehow, there are no chapters dedicated to how Republicans are decimating research and firing experts.

It feels like there’s some magic spice our best models are missing out on. Preorganization of the binding site seems like one huge thing that can get you from 0/100 to 1/100, but I’m super curious what else is out there to learn
