What's the signification of nuclear vacuoles in human sperm?
(2008-07-01)
The aim of this study was to determine the extent of DNA fragmentation and the presence of single/denatured or double stranded of DNA in sperm with large nuclear vacuoles (LNV) selected by high-magnification. A total of ...

Animal Mitochondrial DNA Replication
(2016-01-01)
Recent advances in the field of mitochondrial DNA (mtDNA) replication highlight the diversity of both the mechanisms utilized and the structural and functional organization of the proteins at mtDNA replication fork, despite ...
The Essential, Ubiquitous Single-Stranded DNA-Binding Proteins
(2021-01-01)
Maintenance of genomes is fundamental for all living organisms. The diverse processes related to genome maintenance entail the management of various intermediate structures, which may be deleterious if unresolved. The most ...
DNA Double-Strand Breaks: A Double-Edged Sword for Trypanosomatids
(2021-04-15)
For nearly all eukaryotic cells, stochastic DNA double-strand breaks (DSBs) are one of the most deleterious types of DNA lesions. DSB processing and repair can cause sequence deletions, loss of heterozygosity, and chromosome ...
The natural absence of RPA1N domain did not impair Leishmania amazonensis RPA-1 participation in DNA damage response and telomere protection.
(2013-04-01)
We have previously shown that the subunit 1 of Leishmania amazonensis RPA (LaRPA-1) alone binds the G-rich telomeric strand and is structurally different from other RPA-1. It is analogous to telomere end-binding proteins ...
Tolerance of DNA mismatches in dmc1 recombinase-mediated DNA strand exchange
(American Society for Biochemistry and Molecular Biology, 2016-03)
Recombination between homologous chromosomes is required for the faithful meiotic segregation of chromosomes and leads to the generation of genetic diversity. The conserved meiosis-specific Dmc1 recombinase catalyzes ...
Stimulation of Variant Forms of the Mitochondrial DNA Helicase Twinkle by the Mitochondrial Single-Stranded DNA-Binding Protein
(2021-01-01)
Defects in mitochondrial DNA (mtDNA) maintenance may lead to disturbances in mitochondrial homeostasis and energy production in eukaryotic cells, causing diseases. During mtDNA replication, the mitochondrial single-stranded ...
