Recording physiological history of cells with chemical labeling
Kai Johnsson, Julien Hiblot, Ling Hai
Recordings of the physiological history of cells provide insights into biological processes, yet obtaining such recordings is a challenge. To address this, we introduce a method to record transient cellular events for later analysis. We designed proteins t ...
Amer Assoc Advancement Science2024From Sequence to Dynamics to Function: Computational Design of Allostery and Ligand Selectivity in G-Protein Coupled Receptors
The phenomenon of allostery, a general property in proteins that has been heralded as "the second secret of life" remains elusive to our understanding and even more challenging to incorporate into protein design. One example of allosteric proteins with gre ...
EPFL2024Towards Uncovering the Mechanisms of Electrophile Sensing and Signaling
Native reactive electrophile species (RES) such as 4-hydroxynonenal (HNE) act as cellular signals through covalent modification of kinetically-privileged electrophile sensor proteins. Research efforts in the field focus mainly on identifying these sensor p ...
EPFL2023Bioaccumulation and molecular effects of carbamazepine and methylmercury co-exposure in males of Dreissena polymorpha
Florian Frédéric Vincent Breider, Dominique Grandjean, Nguyên Thiên Kim Lê, Claudia Cosio
Dreissena polymorpha is a bivalve promising for biomonitoring in freshwater ecosystems thanks to its abundance and high filtration activity allowing rapid uptake of toxicants and identification of their negative effects. Nonetheless, we still lack knowledg ...
2023Quantifying single-cell diacylglycerol signaling kinetics after uncaging
Milena Maria Schuhmacher, Pavel Barahtjan
Studying the role of molecularly distinct lipid species in cell signaling remains challenging due to a scarcity of methods for performing quantitative lipid biochemistry in living cells. We have recently used lipid uncaging to quantify lipid -pro-tein affi ...
Cambridge2023Rules and mechanisms governing G protein coupling selectivity of GPCRs
Bruno Emanuel Ferreira De Sousa Correia, Pablo Gainza Cirauqui
G protein-coupled receptors (GPCRs) convert extracellular stimuli into intracellular signaling by coupling to heterotrimeric G proteins of four classes: Gi/o, Gq, Gs, and G12/13. However, our understanding of the G protein selectivity of GPCRs is incomplet ...
Cambridge2023Computational rewiring of allosteric pathways reprograms GPCR selective responses to ligands
Patrick Daniel Barth, Mahdi Hijazi, Aurélien Laurent Jean-Charles Oggier, Dániel Kéri
G-protein-coupled receptors (GPCRs) are the largest class of cell surface receptors and drug targets, and respond to a wide variety of chemical stimuli to activate diverse cellular functions. Understanding and predicting how ligand binding triggers a speci ...
bioRxiv2022Hitting the Bullseye: Endogenous Electrophiles Show Remarkable Nuance in Signaling Regulation
Yimon Aye, Pierre Alexander Miranda Herrera
ABSTRACT: Our bodies produce a host of electrophilic species that can label specific endogenous proteins in cells. The signaling roles of these molecules are under active debate. However, in our opinion, it is becoming increasingly likely that electrophile ...
AMER CHEMICAL SOC2022Rational design of protein switches: applications in synthetic biology and cancer immunotherapy
Synthetic biology aims to engineer cells as miniature biological devices to sense, process, and respond to exogenous stimuli. Protein switches are designed to sense and respond to various molecular queues in a fast and specific manner, which fits the requi ...
EPFL2022Hierarchical tensile structures with ultralow mechanical dissipation
Tobias Kippenberg, Alberto Beccari, Amirali Arabmoheghi, Nils Johan Engelsen, Sergey Fedorov
Structural hierarchy is found in myriad biological systems and has improved man-made structures ranging from the Eiffel tower to optical cavities. In mechanical resonators whose rigidity is provided by static tension, structural hierarchy can reduce the di ...
