TLDR
Many proteins that lack intrinsic globular structure under physiological conditions have now been recognized, and it appears likely that their rapid turnover, aided by their unstructured nature in the unbound state, provides a level of control that allows rapid and accurate responses of the cell to changing environmental conditions.About:

Protein dynamics and motions in relation to their functions: several case studies and the underlying mechanisms
TL;DR: The mechanisms underlying protein dynamics and protein–ligand binding, including the concept of the free energy landscape (FEL) of the protein–solvent system, how the ruggedness and variability of FEL determine protein’s dynamics, and how the three ligand-binding models, the lock-and-key, induced-fit, and conformational selection are rationalized based on the FEL theory are discussed in depth.

Structure of the transition state for the binding of c-Myb and KIX highlights an unexpected order for a disordered system
TL;DR: Unexpectedly, the mechanism of recognition between an intrinsically unstructured protein and its partner is found to occur with a very high degree of geometrical precision, suggesting that a potential value of disorder is not, in this case, to be searched in the speeding up of the reaction thanks to an increased capture radius.

The cardiokine story unfolds: ischemic stress-induced protein secretion in the heart
TL;DR: This review focuses on how the ischemic heart maintains or even increases the release of select cardiokines that regulate important cellular processes in the heart, including excitation-contraction coupling, hypertrophic growth, myocardial remodeling and stem cell function, in ways that moderate isChemic damage and enhance cardiac repair.
Journal ArticleDOI
Protein folding and misfolding on surfaces.
TL;DR: The energy landscape theory is proposed which provides a consistent framework to better understand how a protein folds rapidly and efficiently to the compact, biologically active structure.
Journal ArticleDOI
The N-terminal domain of the phosphoprotein of Morbilliviruses belongs to the natively unfolded class of proteins.
TL;DR: It is shown by two complementary computational approaches that PNT belongs to the recently described class of natively unfolded proteins, further confirming its reported similarity with acidic activation domains of cellular transcription factors.

The Transcriptional Coactivators p300 and CBP Are Histone Acetyltransferases
TL;DR: It is demonstrated that p300/CBP acetylates nucleosomes in concert with PCAF, a novel class of acetyltransferases in that it does not have the conserved motif found among various other acetyl transferases.

The Structural Basis of Estrogen Receptor/Coactivator Recognition and the Antagonism of This Interaction by Tamoxifen

TL;DR: Crystal structures of the human estrogen receptor alpha (hER alpha) ligand-binding domain (LBD) and the OHT-LBD complex reveal the two distinct mechanisms by which structural features of OHT promote this "autoinhibitory" helix 12 conformation.

Crystal structure of a SNARE complex involved in synaptic exocytosis at 2.4 Å resolution
TL;DR: The X-ray crystal structure of a core synaptic fusion complex containing syntaxin-1A, synaptobrevin-II and SNAP-25B reveals a highly twisted and parallel four-helix bundle that differs from the bundles described for the haemagglutinin and HIV/SIV gp41 membrane-fusion proteins.

Conversion of alpha-helices into beta-sheets features in the formation of the scrapie prion proteins.

TL;DR: It is argued that the conversion of alpha-helices into beta-sheets underlies the formation of PrPSc, and it is likely that this conformational transition is a fundamental event in the propagation of prions.

A signature motif in transcriptional co-activators mediates binding to nuclear receptors.
TL;DR: It is proposed that the LXXLL motif is a signature sequence that facilitates the interaction of different proteins with nuclear receptors, and is thus a defining feature of a new family of nuclear proteins.
