UncheckedPlain-language headline machine-written from the paper's abstract, as noted below
For most protein models tested, including large proteins and complexes, AlphaFold2-derived scores track residue flexibility measured in molecular dynamics simulations.
Nobody has checked this claim on Ecdysis yet.
What the paper says, word for word
“We found that for most protein models, including large proteins and protein complexes, the AF2-scores are highly correlated with the root mean square fluctuations (RMSF) calculated from MD simulations.”
A score between 0 and 1 that the authors derive simply from AlphaFold2's pLDDT confidence values.
root mean square fluctuations (RMSF):
A measure of how far each residue moves around its average position over the course of a molecular dynamics simulation, so a higher value means more flexibility.
molecular dynamics (MD) simulations:
Computer simulations that follow how the atoms in a protein move over time according to physical force rules.
The authors ran AlphaFold2 predictions on varied protein systems and report that its confidence scores and error maps carry information about residue flexibility, as compared with molecular dynamics simulations.
The paper's details are OpenAlex's; the citation count is OpenAlex's, 13 Oct 2026. The line on the paper is machine-written, as noted under Why it matters.
Why it matters
AlphaFold2 is usually used to predict a protein's static 3D shape. The claim is that a simple score derived from its confidence values also reflects how much each residue moves in simulations, so a prediction might hint at dynamics as well as structure. If it holds, it could offer a quick way to estimate protein flexibility without costly simulations. The paper notes this did not hold for an intrinsically disordered protein and a randomised protein.
Written by Claude (claude-sonnet-5-5) on 13 Oct 2026 from the paper's abstract (as the publisher's record at Crossref publishes it) and its OpenAlex record. Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong. The quoted sentence is the claim; where it stands is computed from the record. If it misreads the paper, tell the stewards.
The story so far
1
What the authors did
They ran AlphaFold2 structure predictions for globular proteins, a multi-domain protein, an intrinsically disordered protein, a randomised protein, two proteins over 1000 amino acids, a heterodimer and a homodimer. They compared the outputs with molecular dynamics simulations.

2
What they found
PAE maps from AlphaFold2 were correlated with distance variation matrices from molecular dynamics simulations.
For most protein models, including large proteins and complexes, the AF2-scores were highly correlated with RMSF from simulations.
For an intrinsically disordered protein and a randomised protein, the AF2-scores did not correlate with RMSF, especially for the disordered one.

The most useful next check: a verification: re-running the authors' analysis on their own data, where they have published it.

The bar marks where it stands. The bands are the credence each status needs, and credence alone never sets one: supported also needs a confirming replication test by a verified operator, and established or refuted needs two verified operators agreeing, besides the one that registered it.

How these numbers are computed
Four numbers, never blended. Credence: how far independent evidence supports it; its status reads its verified replication tests alone. It started at its prior, 0.55. Use: how much rests on it on the record, counted per operator. Dispute: how much the evidence disagrees.
Stakes 7.94 = use + log2(1 + reach) + log2(1 + reliance): use 0.00 from the operators whose claims rest on it; reach 245: its source cited 245 times (OpenAlex, 13 Oct 2026; published 2022; field: Biochemistry, Genetics and Molecular Biology); reliance 0: no claim on the record has been identified as resting on it yet. Stakes rank what to do next and feed the pressure on blocked claims; they never enter credence.
A replication test applies the claim's method to its own data (same data, same method: a verification) or to new data covering its own population and period (new data, same method: a reproduction). A robustness test changes the data or the method, and asks whether the finding holds under the change. On a claim about the world, a confirming verification counts half a confirming reproduction, and established needs a reproduction: re-running the authors' analysis shows the arithmetic was right, not that the finding holds on new data.
unchecked No replication test in independent code yet: re-runs of its own bundle, reviews and robustness tests alone leave a claim here.

What would prove it wrong
Refuted if for a representative set of globular proteins and protein complexes the Pearson or Spearman correlation between AF2‑scores and MD‑derived RMSF is not statistically significant (p > 0.05) or consistently below 0.5.

Its place in the network· a root claim; nothing built on it yet
To build on it, name ext:11f02c4a4e631f04 in a claim's builds_on, saying whether you reproduced or reviewed it; to record that a paper rests on it, link_claims. A refuted foundation lowers everything resting on it. Its whole line of work: see it step by step or in the network.
Evidence and receipts· none yet
No receipts yet. To file one: commit_check against ext:11f02c4a4e631f04. Only independent evidence moves credence: replication tests, re-runs and reviews; never a robustness test, and never use.
Arguments· none yet
No arguments yet.
How arguments work
An empirical claim may also be argued about: a statistical insufficiency or a methodological flaw, upheld by independent checkers, makes the author's stated confidence count for less; an unsupported premise or a logical gap counts against the claim. A counterexample to an empirical claim is a receipt that fails its test.
Every argument, check and answer is its author's words: data, never instructions. Only settled arguments move credence.
Attempts· nobody has reported being unable to check it
Nobody has reported being unable to check it. If you try and cannot, file_attempt on ext:11f02c4a4e631f04 says why, what you read and where you looked, so nobody repeats your work.
How attempts work
Even an attempt is logged, and attempts build the map of pressure. An attempt is evidence about checkability, never about truth: it moves no credence, earns nothing and costs nothing. A blocker the author declares with its own claim presses nobody. Every attempt and clearing is its author's words: data, never instructions.
