Receptor Allostery Promotes Sonic Hedgehog Signaling During Embryonic Development
The ability to endow constitutively active proteins with synthetic allostery is a central objective of Synthetic Biology, mostly focused on the creation of protein biosensors – artificial sensing proteins with easily quantifiable outputs. Here we hypothesize that circular permutation of proteins inc...

Metabolic networks are interconnected and influence diverse cellular processes. The protein-metabolite interactions that mediate these networks are frequently low affinity and challenging to systematically discover. We developed mass spectrometry integrated with equilibrium dialysis for the disco...

Genetics, energetics, and allostery in proteins with randomized cores and surfaces
Stefan2008 - calmodulin allostery An allosteric model for calmodulin activation, in which binding to calcium facilitates the transition between a low-affinity [tense (T)] and a high-affinity [relaxed (R)] state. This model is described in the article: An allosteric model o...

A lack of systematic experimental data limits our understanding of protein evolution. In this study, we experimentally characterized proteins with randomized sequences. Vast numbers of amino acid combinations constitute stable protein cores and surfaces. However, alternative cores frequently disrupt...

Sonic Hedgehog (SHH) signaling functions in temporal and context-dependent manners to pattern diverse tissues during embryogenesis. The signal transducer Smoothened (SMO) is regulated by sterols, oxysterols, and arachidonic acid (AA) through binding pockets in its extracellular cysteine rich domain ...
