Expression of membrane-associated proteins within single emulsion cell facsimiles [PDF]

, 2012
MreB is a structural membrane-associated protein which is one of the key components of the bacterial cytoskeleton. Although it plays an important role in shape maintenance of rod-like bacteria, the understanding of its mechanism of action is still not ...

A cellular system to study responses to a collision between the transcription complex and a protein‐bound nick in the DNA template

FEBS Letters, EarlyView.
We present the cellular transcription‐coupled Flp‐nick system allowing the introduction of a Top1‐mimicking cleavage complex (Flpcc) at a Flp recognition target site within a controllable LacZ gene. LacZ transcription leads to the collision of RNA polymerase II (RNAPII) with Flpcc, and this causes RNAPII stalling, ubiquitination, and degradation.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

GEFA: Early Fusion Approach in Drug-Target Affinity Prediction [PDF]

arXiv, 2020
Predicting the interaction between a compound and a target is crucial for rapid drug repurposing. Deep learning has been successfully applied in drug-target affinity (DTA) problem. However, previous deep learning-based methods ignore modeling the direct interactions between drug and protein residues.

Structural characterization of viral fusion proteins [PDF]

Current Biology, 1995
Infection by enveloped viruses is initiated by the fusion of viral and cellular membranes. In many cases, the viral membrane proteins that mediate fusion must undergo conformational changes to become active. Influenza hemagglutinin, for example, is activated by a dramatic conformational rearrangement, triggered by the low pH of the intracellular ...

SNAC-tag for sequence-specific chemical protein cleavage. [PDF]

, 2019
Site-specific protein cleavage is essential for many protein-production protocols and typically requires proteases. We report the development of a chemical protein-cleavage method that is achieved through the use of a sequence-specific nickel-assisted ...

Disruption of HOX activity leads to cell death that can be enhanced by the interference of iron uptake in malignant B cells. [PDF]

, 2010
The HOX genes encode a family of transcription factors that are dysregulated in several malignancies and have been implicated in oncogenesis and cancer cell survival.

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

FEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

In silico Design, and In vitro Expression of a Fusion Protein Encoding Brucella abortus L7/L12 and SOmp2b Antigens

Advanced Biomedical Research, 2018
Background: L7/L12 is a protective antigen conserved in main Brucella pathogens and is considered as potential vaccine candidate. Outer membrane protein 2b is an immunogen conserved in all Brucella pathogens.

Fusion Phage as a Bioselective Nanomaterial : Evolution of the Concept [PDF]

Dans European Nano Systems Worshop - ENS 2006, Paris : France (2006), 2007
Multibillion-clone landscape phage display libraries were prepared by the fusion of the phage major coat protein pVIII with foreign random peptides. Phage particles and their proteins specific for cancer and bacterial cells were selected from the landscape libraries and exploited as molecular recognition interfaces in detection, gene- and drug-delivery
