Do you work on DNA or RNA protein complexes? π§¬

Super early discount is ending this Sunday so register now! π
Interesting point. I suppose a precondition for the rule to work is that there is sufficient chemical βorthogonalityβ to make different phases coexist, which I doubt applies to a cell.
Please elaborate if possible
My answer:
xtallization in vitro can't predict xtallization in cells as:
1) The crystallising object is different in cells (binding, PTMs, etc.)
2) Cytosol and crystallisation buffer are distinct solvents
For precisely the same reasons, LLPS in this assay does not predict LLPS in vivo
π ok but at least to dismiss the threat of a new alternative religion like the liquid-solid phase transition predicted by in vitro crystallization some arguments are required!
I am curious to see if answers come up
Beautiful indeed! (But not ours though!)
If I claimed this liquid-to-solid phase transition assay on a pure protein in vitro predicts the same transition to happen in cells, what counterarguments would you raise?
Would the same counterarguments apply to a liquid-to-liquid phase transition assay on the same pure protein in vitro?
@joann-trejo.bsky.social, @marymunson4.bsky.social and I have a commentary in @natcellbio.nature.com on recent attacks on DEI in biomedical research: "If scientific research, especially biomedical research, is meant to serve everyone, then it requires that everyone has an opportunity to participate"
Our paper is now out in Nature:

Re-gain of function (synthetic viability from mixing perturbations) may result from removing two different parts of a sequence. Very hard to make conclusions on "chemistry" without a detailed mechanism in my view.
Thank you for these comments. The IDRs of Abf1 works next to DNA-binding domains. Their local concentration is very high. Motifs may be very short, and the IDR may have coexisting activation and repressive functions that may lead to unexpected phenotypes (including dominant effects).
Something of general value, however:
Homotypic phase separation of IDRs is so implausible that it can only be a fantasy.
This fantasy has distracted both the science community and the publication system from supporting real progress in molecular biology
3/ The reason? There is no intrinsic sequence grammar independent of specific function and binding partners! Many different mechanistic models may explain the data.
Why does it matters? Because the hardest part of the job is to unravel the molecular mechanism that explains the observations...
2/ I tend to disagree. The study addresses correlations between the sequence variants of IDR2 of Abf1 and viability.
In my view, without a detailed mechanistic model, mutations cannot be understood and claimed to support a general principle...
1/ This is a nice and thorough study that "does not strongly support a homotypic phase-separation-based model" and supports sequence and "chemically specific interactions" for IDRs.
On the conceptual level, the title suggests general mechanistic conclusions can be inferred...
We're launching a research lab at SMART. Shenzhen Medical Academy for Research and Translation is a newly established institute with long-term funding mechanisms for internal and external investigators. At full capacity SMART aims to support up to 400 labs.

The discovery of the first kinetochore proteins (CENP-A, CENP-B, CENP-C) was reported by Bill Earnshaw and Naomi Rothfield in 1985 in Chromosoma. Forty years later, Chromosoma/Chromosome Research has published a special issue (most articles are open access)
