Gene expression noise accelerates the evolution of a biological oscillator
Lin, Y. T., & Buchler, N. E. (2022, March 23). (Vol. 3). Vol. 3.
TL;DR:
It is shown that noise counter-intuitively accelerates the evolution of a biological oscillator and, thus, can impart a benefit to living organisms and suggest that noise can help dynamical systems evolve or learn new behavior by revealing cryptic dynamic phenotypes outside the bifurcation point.

MeSH headings : Amino Acid Motifs; Amino Acid Sequence; Cell Cycle / genetics; Cell Cycle / physiology; Cyclin B / chemistry; Cyclin B / genetics; Cyclin B / physiology; Cyclin-Dependent Kinases / genetics; Cyclin-Dependent Kinases / physiology; Cyclins / genetics; Cyclins / physiology; DNA Replication; Gene Expression Regulation, Fungal; Hydrophobic and Hydrophilic Interactions; Molecular Sequence Data; Origin Recognition Complex / chemistry; Origin Recognition Complex / genetics; Origin Recognition Complex / physiology; Protein Structure, Tertiary; Saccharomyces cerevisiae / genetics; Saccharomyces cerevisiae / physiology; Saccharomyces cerevisiae Proteins / chemistry; Saccharomyces cerevisiae Proteins / genetics; Saccharomyces cerevisiae Proteins / physiology; Signal Transduction / genetics; Signal Transduction / physiology
TL;DR:
The observations as well as work from other groups suggest that HP-RXL interactions are functionally important for cyclin-Cdk signaling to other targets, and the evolutionary conservation of the HP motif suggests that it allows cyclins to carry out important and specialized functions.

Surveying determinants of protein structure designability across different energy models and amino-acid alphabets: A consensus
The Journal of Chemical Physics.
TL;DR:
A solvation model was demonstrated to give identical designability results to previous models, and was shown to be inherently related to thermodynamically relevant energetic measures of protein folding, such as the foldability F and energy gap Δ10.

Effect of alphabet size and foldability requirements on protein structure designability
Proteins: Structure, Function and Genetics, 34(1), 113–124.
Contributors: N. Buchler & R. Goldstein *
TL;DR:
The designability of lattice proteins over a wide range of amino acid alphabets and foldability requirements is compared and it was noticed that those structures that were highly designable for the two‐letter amino acidAlphabet are not especially designable with higher‐letter alphABets.

Universal correlation between energy gap and foldability for the random energy model and lattice proteins
The Journal of Chemical Physics.
TL;DR:
The random energy model is revisited to derive the statistical distributions of the various energy gaps and foldability and the resulting joint distribution allows us to explicitly demonstrate the positive foldability of proteins.

Protein Heteronuclear NMR Assignments Using Mean-Field Simulated Annealing
Journal of Magnetic Resonance, 125(1), 34–42.
Contributors: N. Buchler *, E. Zuiderweg *, H. Wang * & R. Goldstein *
MeSH headings : Computer Simulation; Magnetic Resonance Spectroscopy / methods; Molecular Weight; Proteins / chemistry
TL;DR:
A mean-field method that reports the resonance assignments in a probabilistic fashion, displaying the certainty of assignments in an unambiguous and quantitative manner was applied to the NMR data of the 172-residue peptide-binding domain of the E. coli heat-shock protein, DnaK.
