Expression of human RECQL5 in Saccharomyces cerevisiae causes transcription defects and transcription-associated genome instability
(Springer Nature, 2024-05-26)
RECQL5 is a member of the conserved RecQ family of DNA helicases involved in the maintenance of genome stability that is specifically found in higher eukaryotes and associates with the elongating RNA polymerase II. To ...
Article
BRCA1/BARD1 ubiquitinates PCNA in unperturbed conditions to promote continuous DNA synthesis
(Nature Research, 2024-05-20)
Deficiencies in the BRCA1 tumor suppressor gene are the main cause of hereditary breast and ovarian cancer. BRCA1 is involved in the Homologous Recombination DNA repair pathway and, together with BARD1, forms a heterodimer ...
Article
SIN3A histone deacetylase action counteracts MUS81 to promote stalled fork stability
(CELL PRESS (Elsevier), 2024)
During genome duplication, replication forks (RFs) can be stalled by different obstacles or by depletion of replication factors or nucleotides. A limited number of histone post-translational modifications at stalled RFs ...
Article
Functional characterization and structural modelling of Helianthus annuus (sunflower) ketoacyl-CoA synthases and their role in seed oil composition
(Springer Nature, 2019)
Main conclusion: The enzymes HaKCS1 and HaKCS2 are expressed in sunflower seeds and contribute to elongation of C18 fatty acids, resulting in the C20–C24 fatty acids in sunflower oil. Most plant fatty acids are produced ...
Article
Cleavage factor I links transcription termination to DNA damage response and genome integrity maintenance in Saccharomyces cerevisiae
(Public Library of Science, 2014)
During transcription, the nascent pre-mRNA undergoes a series of processing steps before being exported to the cytoplasm. The 3′-end processing machinery involves different proteins, this function being crucial to cell ...

Regulation of finP transcription by DNA adenine methylation in the virulence plasmid of Salmonella enterica
(American Society for Microbiology, 2005-08)
DNA adenine methylase (Dam -) mutants of Salmonella enterica serovar Typhimurium contain reduced levels of FinP RNA encoded on the virulence plasmid. Dam methylation appears to regulate finP transcription, rather than FinP ...
Article
Fusarium photoreceptors
(MDPI, 2023-03-04)
Light is an important modulating signal in fungi. Fusarium species stand out as research models for their phytopathogenic activity and their complex secondary metabolism. This includes the synthesis of carotenoids, whose ...
Article
Genome-scale mapping of DNA damage suppressors through phenotypic CRISPR-Cas9 screens
(Cell Press, 2023-08-03)
To maintain genome integrity, cells must accurately duplicate their genome and repair DNA lesions when they occur. To uncover genes that suppress DNA damage in human cells, we undertook flow-cytometry-based CRISPR-Cas9 ...
Article
Lack of reelin modifies the gene expression in the small intestine of mice
(Springer Nature, 2012)
We recently demonstrated that the mucosa of the small intestine of the rat expresses reelin and some components of its signaling system. The current study evaluates whether reelin affects the intestinal gene expression ...
Article
Intergeneric hybrids of Saccharomyces cerevisiae and Zygosaccharomyces fermentati obtained by protoplast fusion
(American Society for Microbiology, 1986)
To obtain strains that are able to efficiently produce ethanol from different carbohydrates, mainly cellulose hydrolysates, several species of the genus Candida and a Zygosaccharomyces fermentati ...
