TIA-1 Self-Multimerization, Phase Separation, and Recruitment into Stress Granules Are Dynamically Regulated by Zn2+

Cell Reports, 2018
Summary: Stress granules are non-membranous structures that transiently form in the cytoplasm during cellular stress, where they promote translational repression of non-essential RNAs and modulate cell signaling by sequestering key signal transduction ...

Analysis of multimerization of the SARS coronavirus nucleocapsid protein

Biochemical and Biophysical Research Communications, 2004
Severe Acute Respiratory Syndrome (SARS), an emerging disease characterized by atypical pneumonia, has recently been attributed to a novel coronavirus. The genome of SARS Coronavirus (SARS-CoV) has recently been sequenced, and a number of genes identified, including that of the nucleocapsid protein (N).

HIV-1 integrase tetramers are the antiviral target of pyridine-based allosteric integrase inhibitors

eLife, 2019
Allosteric HIV-1 integrase (IN) inhibitors (ALLINIs) are a promising new class of antiretroviral agents that disrupt proper viral maturation by inducing hyper-multimerization of IN.

Structural Basis for Inhibitor-Induced Aggregation of HIV Integrase. [PDF]

PLoS Biology, 2016
The allosteric inhibitors of integrase (termed ALLINIs) interfere with HIV replication by binding to the viral-encoded integrase (IN) protein. Surprisingly, ALLINIs interfere not with DNA integration but with viral particle assembly late during HIV ...

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

Advanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Expression of acid cleavable Asp-Pro linked multimeric AFP peptide in E. coli

Journal of Genetic Engineering and Biotechnology, 2021
Background Difficult to express peptides are usually produced by co-expression with fusion partners. In this case, a significant mass part of the recombinant product falls on the subsequently removed fusion partner.

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

Cytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

A chemical approach to the construction of multimeric protein assemblies [PDF]

Structure, 1995
Chemical and enzymatic ligation approaches provide a general route to the synthesis of proteins whose primary structure is not restricted to the genetic code. Thus, one can replace key residues in a protein with unnatural amino acids whose chemical or structural properties can be tailored to probe specific aspects of function. In addition, isotopically
