OpenAI doesn't report a single number for its climate impacts - not anywhere, in any way, shape or form.
It sounds kind of obvious but the fact that a company with such incredible electricity hunger isn't disclosing basic information about its energy consumption and associated emissions is v bad..

Years after the idea and preliminary experiments, Claire Coupland's amazing structure of the endogenous vacuolar- or vesicular-ATPase in its NATIVE vesicle is now in bioRxiv "High resolution cryo-EM of V-ATPase in native synaptic vesicles"

this is also correctly predicted

yep correct, the small protein is the green box in bottom right. This is a large membrane protein. The interacting region of the first protein can be verified by homology modelling. All the high confidence regions predicted by AF3 can be verified by homology, and inter domain packing is also good.

PAE plot from AF3
PAE looks like this. The iPTM score is also 0.74, so these helices are really unreliable, and they take up a considerable amount of amino acids in the total sequence.

ah I see, thanks

thanks, yeah I figured because manual inspection of the sequence and IDR prediction server also spit out similar disordered behaviour for these regions. Most of these are just poly-Ns, some need to be checked more carefully.

ohh do you have a visual example of 'curled' models?

A 500 kDa protein model generated by AlphaFold 3
AF3 model of the protein with the binding partner
AF3 predictions for a 500 kDa protein without (left) and with (right) a known 40 kDa binding partner. Apparently disordered regions collapsing into low confidence cytosolic helices. Is AF hallucinating these helices?

yep, it was apparently a fabrication issue because we didn't notice anything strange while handling and preparing this grid, it was only clear at the screening stage
