Molecular Docking for the Development of Alternative Therapies against Leishmaniasis

Chemistry Proceedings, 2023
Topoisomerases play a pivotal role in regulating the topological structure of DNA during fundamental processes such as transcription, DNA repair, or DNA replication; because of this, topoisomerases are biological targets in pathogenic microorganisms or ...

Drf1-dependent Kinase Interacts with Claspin through a Conserved Protein Motif [PDF]

, 2010
The Dbf4/Drf1-dependent kinase (DDK) is required for the initiation of DNA replication in eukaryotes. Another protein, Claspin, mediates the activation of a cellular checkpoint response to stalled replication forks and is also a regulator of replication.

Targeting of the Fun30 nucleosome remodeller by the Dpb11 scaffold facilitates cell cycle-regulated DNA end resection

eLife, 2017
DNA double strand breaks (DSBs) can be repaired by either recombination-based or direct ligation-based mechanisms. Pathway choice is made at the level of DNA end resection, a nucleolytic processing step, which primes DSBs for repair by recombination ...

Attenuation of reverse transcriptase facilitates SAMHD1 restriction of HIV-1 in cycling cells

Retrovirology, 2023
Background SAMHD1 is a deoxynucleotide triphosphohydrolase that restricts replication of HIV-1 in differentiated leucocytes. HIV-1 is not restricted in cycling cells and it has been proposed that this is due to phosphorylation of SAMHD1 at T592 in these ...

Dicer prevents genome instability in response to replication stress [PDF]

, 2019
Dicer, an endoribonuclease best-known for its role in microRNA biogenesis and RNA interference pathway, has been shown to play a role in the DNA damage response and repair of double-stranded DNA breaks (DSBs) in mammalian cells.

Adenovirus DNA Replication [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Adenoviruses have attracted much attention as probes to study biological processes such as DNA replication, transcription, splicing, and cellular transformation. More recently these viruses have been used as gene-transfer vectors and oncolytic agents.

An enhancer of DNA replication [PDF]

Journal of Bacteriology, 1988
cmp, a nucleotide sequence element in the plasmid pT181 of Staphylococcus aureus, acts as an enhancer of DNA replication. When cmp is present on an unrelated vector along with the pT181 origin of replication, it increases the ability of the linked pT181 origin to compete with a coresident pT181 plasmid for the initiator protein RepC.

MCM2-7 ring closure involves the Mcm5 C-terminus and triggers Mcm4 ATP hydrolysis

Nature Communications
The eukaryotic helicase MCM2-7, is loaded by ORC, Cdc6 and Cdt1 as a double-hexamer onto replication origins. The insertion of DNA into the helicase leads to partial MCM2-7 ring closure, while ATP hydrolysis is essential for consecutive steps in pre ...
