Rational Design of Phosphorylation-Responsive Coiled Coil-Peptide Assemblies.

peptides and proteins that switch state in response to chemical and physical cues would advance protein design and synthetic biology. Here we report two designed systems that disassemble and reassemble upon site-specific phosphorylation and dephosphorylation, respectively. As starting points, we use hyperthermostable antiparallel and parallel coiled-coil heterotetramers, , AB systems, to afford control in downstream applications.

De novo designed peptides for cellular delivery and subcellular localisation.

Increasingly, it is possible to design peptide and protein assemblies de novo from first principles or computationally. This approach provides new routes to functional synthetic polypeptides, including designs to target and bind proteins of interest. Much of this work has been developed in vitro.

Assessing remission in major depressive disorder and generalized anxiety disorder clinical trials with the discan metric of the Sheehan disability scale.

Relatively little research has focused on the relationship between functional remission and symptomatic remission in mood and anxiety disorders. This study investigates the relationship and synchrony between symptomatic and functional remission in outpatients with major depressive disorder (MDD) and generalized anxiety disorder (GAD). Using data from three MDD (N=1419) and four GAD (N=1847) randomized, placebo-controlled duloxetine studies, we calculated the percentages of patients meeting symptomatic, functional, and combined functional-symptomatic remission criteria for each disorder.
