Direct observation of silver nanoparticle-ubiquitin corona formation [PDF]
, 2012 Upon entering physiological environments, nanoparticles readily assume the form of a nanoparticle-protein corona that dictates their biological identity. Understanding the structure and dynamics of nanoparticle-protein corona is essential for predicting the fate, transport, and toxicity of nanomaterials in living systems and for enabling the vast ...

Cloning and bioinformatics analysis of an ubiquitin gene of the rice stem borer, Chilo suppressalis Walker (Lepidoptera: Pyralidae) [PDF]
, 2013 Ubiquitin which has the function of selective protein degradation may play an important role in the regulation of insect growth and development. The coding sequence of an ubiquitin gene from the larvae of the rice stem borer, Chilo suppressalis Walker ...

Ubiquitin and Ubiquitin-Like Modifications of the p53 Family
Neoplasia, 2006 Regulation of p53 by the ubiquitin-proteasomal pathway has been studied considerably. Studies have also demonstrated that the ubiquitin-like proteins SUMO-1 and NEDD8 modify p53. Similarly, p63 and p73 are subject to regulation by ubiquitin and ubiquitin-like modifications, and perturbations of these pathways in the regulation of the p53 family have ...

Ubiquitin and Ubiquitin-Like Proteins in Protein Regulation [PDF]
Circulation Research, 2007 The discovery of the ubiquitin system was awarded with the Nobel Prize in Chemistry in 2004. Labeling of intracellular proteins for degradation by a multienzymatic complex, called the proteasome, was identified as the main function of this system. Subsequently, it was discovered that the attachment of ubiquitin to proteins can modify their function ...

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.

New force replica exchange method and protein folding pathways probed by force-clamp technique [PDF]
, 2007 We have developed a new extended replica exchange method to study thermodynamics of a system in the presence of external force. Our idea is based on the exchange between different force replicas to accelerate the equilibrium process. We have shown that the refolding pathways of single ubiquitin depend on which terminus is fixed.

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 ...

Dipolar response of hydrated proteins [PDF]
, 2011 The paper presents an analytical theory and numerical simulations of the dipolar response of hydrated proteins. The effective dielectric constant of the solvated protein, representing the average dipole moment induced at the protein by a uniform external field, shows a remarkable variation among the proteins studied by numerical simulations. It changes

Structure and recognition of polyubiquitin chains of different lengths and linkage [PDF]
, 2011 The polyubiquitin signal is post-translationally attached to a large number of proteins, often directing formation of macromolecular complexes resulting in the translocation, assembly or degradation of the attached protein.
