Quantitative essentiality in a reduced genome: a functional, regulatory and structural fitness map [PDF]

open access: yesMolecular Systems Biology
Essentiality studies have traditionally focused on coding regions, often overlooking other small genetic regulatory elements. To address this, we combined transposon libraries containing promoter or terminator sequences to obtain a high-resolution ...

Increased leukotoxin production: Characterization of 100 base pairs within the 530 base pair leukotoxin promoter region of Aggregatibacter actinomycetemcomitans

open access: yesScientific Reports, 2017
Aggregatibacter actinomycetemcomitans leukotoxin (LtxA) is a major virulence factor that kills leukocytes permitting it’s escape from host immune surveillance. A. actinomycetemcomitans strains can produce high or low levels of toxin.

5’ and 3’ untranslated regions strongly enhance performance of geminiviral replicons in Nicotiana benthamiana leaves [PDF]

open access: yesFrontiers in Plant Science, 2016
We previously reported a recombinant protein production system based on a geminivirus replicon that yields high levels of vaccine antigens and monoclonal antibodies in plants.

Protocol for the establishment of a serine integrase-based platform for functional validation of genetic switch controllers in eukaryotic cells. [PDF]

open access: yesPLoS ONE
Serine integrases (Ints) are a family of site-specific recombinases (SSRs) encoded by some bacteriophages to integrate their genetic material into the genome of a host.

Molecular diversity and phylogenetic characterization of the invA gene in non-typhoidal Salmonella from domestic animals and wildlife in Zambia [PDF]

open access: yesVeterinary World
Background and Aim: Non-typhoidal Salmonella remains a significant zoonotic pathogen with substantial implications for animal and public health, particularly in regions where domestic animals and wildlife share ecological interfaces. The invasion protein

A Genome-Wide Activity Assessment of Terminator Regions in Saccharomyces cerevisiae Provides a ″Terminatome″ Toolbox

open access: yes, 2016
The terminator regions of eukaryotes encode functional elements in the 3′ untranslated region (3′-UTR) that influence the 3′-end processing of mRNA, mRNA stability, and translational efficiency, which can modulate protein production.

Synthetic refactor of essential genes decodes functionally constrained sequences in yeast genome

open access: yesiScience, 2022
Summary: The relationship between gene sequence and function matters for fundamental and practical reasons. Here, yeast essential genes were systematically refactored to identify invariable sequences in the coding and regulatory regions.

Genetic Variability of Long Terminal Repeat Region between HIV-2 Groups Impacts Transcriptional Activity [PDF]

open access: yesJournal of Virology, 2020
Over 1 million patients are infected with HIV-2, which is often described as an attenuated retroviral infection. Patients frequently have undetectable viremia and evolve at more slowly toward AIDS than HIV-1-infected patients. Several studies have reported a smaller viral reservoir in peripheral blood mononuclear cells in HIV-2-infected patients than ...
