Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social.

www.sciencedirect.com/science/arti...

Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.

Yikes! In this paper the AlphaFold model of human plasminogen (PDB-8uq6) has been refined into noise (EMD-42462) using Phenix & ISOLDE. For some reason the authors even interpret side-chain interactions:
#cryoEM

Image from the EMD entry EMD-42462 for human plasminogen bound to streptococcal surface enolase. Projections of the map are shown demonstrating no protein features and radial streaks due to overfitting.

EMD-424262 and PDB-8UQ6 opened in ChimeraX. Though the map is stated to be of Human Plasminogen bound to streptococcal surface enolase the authors have modelled only plasminogen in their PDB. The map shows radial streak at the surface indicative of overfitting and no clear density in the centre of the map corresponds to the model.

Figure 5 from the paper describing side chain interactions of human plasminogen from the PDB 8uq6.

Image showing the model to map FSC curve from Phenix which is the software used by the authors to real space refine their PDB into their cryo-EM map. The model to map FSC curve is a flat line showing no correlation exists between the cryo-EM map EMD-42462 and the PDB 8uq6.

Or as the New York Times puts it: “Mr. Trump's budgetary maneuvering appeared unorthodox…”

Mr. Trump's budgetary maneuvering appeared unorthodox, even though it may spare more than 1 million active-duty service members from the financial hardship of missing a paycheck next week. It was not clear how much money the administration had at its disposal, and how long it could rely on accounting moves to pay troops during the shutdown.

A classic case of irresponsible both-sidesism from the NYT. The story is that Trump and MAGA propagandists are lying about Portland to incite a conflict, not that there are different views of the matter.

possibly stupid question - does anyone in #teamtomo or #cryoem recognize these little stacks (from EMPIAR-12549, U2OS cell lamellae)? The green circle is 300Å, and the spacing between the layers is ~50Å. The fourth, bell-shaped thing is something else, also not sure of that one..

You’ve gotta be kidding me.

This WaPo editorial presents a misleading revisionist history of Special Counsel Jack Smith’s criminal cases against Trump.

Then it has the gall to compare that to Trump’s overt targeting of his perceived enemies.

Really embarrassing stuff.

But the mere fact that a legal tool might be available does not mean it should be used. The
current rage over Grassley's revelation shows why. Smith showed little restraint in his pursuit of a former president. He charged Trump for official acts he took as president. He sought a gag order to limit Trump's ability to criticize the prosecution. He tried to accelerate the case to try a leading presidential candidate before the 2024 election.
