FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Synthesis of empty bacterial microcompartments, directed organelle protein incorporation, and evidence of filament-associated organelle movement [PDF]
, 2010 Compartmentalization is an important process, since it allows the segregation of metabolic activities and, in the era of synthetic biology, represents an important tool by which defined microenvironments can be created for specific metabolic functions ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Citrate synthase proteins in extremophilic organisms: Studies within a structure-based model [PDF]
Journal of Chemical Physics 141, 235102 (2014), 2015 We study four citrate synthase homodimeric proteins within a structure-based coarse-grained model. Two of these proteins come from thermophilic bacteria, one from a cryophilic bacterium and one from a mesophilic organism; three are in the closed and two in the open conformations. Even though the proteins belong to the same fold, the model distinguishes

Tobamovirus and Dianthovirus Movement Proteins Are Functionally Homologous
Virology, 1995 The movement proteins (MPs) of tobacco mosaic tobamovirus (TMV) and red clover necrotic mosaic dianthovirus (RCNMV) enlarge plasmodesmata size exclusion limits, transport RNA from cell to cell, and bind nucleic acids in vitro. Despite these functional similarities, they have no sequence homology.

Plasmodesmal Targeting and Accumulation of TMV Movement Protein [PDF]
Plant Signaling & Behavior, 2007 The interaction between tobacco mosaic virus and its host plant cells has been intensively studied as a model for macromolecular trafficking. The observation that GFP-labelled TMV movement protein localises to microtubules led to the suggestion that microtubules are required for the cell to cell movement of the virus.

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation
FEBS Letters, EarlyView.Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

LAST: Latent Space Assisted Adaptive Sampling for Protein Trajectories [PDF]
arXiv, 2022 Molecular dynamics (MD) simulation is widely used to study protein conformations and dynamics. However, conventional simulation suffers from being trapped in some local energy minima that are hard to escape. Thus, most computational time is spent sampling in the already visited regions.
