Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Optimal Design of Cams

Multibody System Dynamics, 2002
The paper presents a methodology which is based on a constrained optimization algorithm where the constraints are the maximum valve lift and timing. The objective is to maximize the time integral of valve area opened to gas flow. Once the optimal lift is known, the cam profile can be developed using inverse kinematic analysis. Finally, the authors give

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Advances in the structures, mechanisms and targeting of molecular chaperones

Signal Transduction and Targeted Therapy
Molecular chaperones, a class of complex client regulatory systems, play significant roles in the prevention of protein misfolding and abnormal aggregation, the modulation of protein homeostasis, and the protection of cells from damage under constantly ...

Optimal design of robots

Robotics: Science and Systems I, 2005
Synthesis of robots may be decomposed into two processes: {\em structural synthesis} (determine the general arrangement of the mechanical structure such as the type and number of joints and the way they will be connected) and {\em dimensional synthesis} (determine the length of the links, the axis and location of the joints, the necessary maximal joint

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

CPUY192018, a potent inhibitor of the Keap1-Nrf2 protein-protein interaction, alleviates renal inflammation in mice by restricting oxidative stress and NF-κB activation

Redox Biology, 2019
The Keap1-Nrf2-ARE pathway regulates the constitutive and inducible transcription of various genes that encode detoxification enzymes, antioxidant proteins and anti-inflammatory proteins and has pivotal roles in the defence against cellular oxidative ...

Optimal Platform Design

CoRR, 2014
There is some overlap between this paper and the paper "Optimal Mechanism Design and Money Burning," which appeared in the STOC 2008 conference and as arXiv:0804.2097. However, the focus of this paper is different, with some of our earlier results omitted and several new results ...
