Initiation of DNA Replication [PDF]

EcoSal Plus, 2010
In recent years it has become clear that complex regulatory circuits control the initiation step of DNA replication by directing the assembly of a multicomponent molecular machine (the orisome) that separates DNA strands and loads replicative helicase at oriC , the unique chromosomal origin of replication.

SARS-CoV-2: from its discovery to genome structure, transcription, and replication

Cell & Bioscience, 2021
SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

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 ...

A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers. [PDF]

, 2019
Cohesin is a multiprotein ring that is responsible for cohesion of sister chromatids and formation of DNA loops to regulate gene expression. Genomic analyses have identified that the cohesin subunit STAG2 is frequently inactivated by mutations in cancer.

The Replication of Polyoma DNA

Journal of General Virology, 1973
Summary Measurement of replicating molecules of polyoma virus DNA after digestion with endonuclease R1 shows that DNA replication is bidirectional, starting predominantly at a specific site. In both large plaque and small plaque polyoma virus DNA this site is 29 ± 2% of the total length of the DNA from the cleavage site of the endonuclease R1.

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 ...

Evidence for a role of Arabidopsis CDT1 proteins in gametophyte development and maintenance of genome integrity [PDF]

, 2012
Meristems retain the ability to divide throughout the life cycle of plants, which can last for over 1000 years in some species. Furthermore, the germline is not laid down early during embryogenesis but originates from the meristematic cells relatively ...

The MRN complex is transcriptionally regulated by MYCN during neural cell proliferation to control replication stress [PDF]

, 2015
The MRE11/RAD50/NBS1 (MRN) complex is a major sensor of DNA double strand breaks, whose role in controlling faithful DNA replication and preventing replication stress is also emerging. Inactivation of the MRN complex invariably leads to developmental and/

DNA Replication in the Archaea [PDF]

Microbiology and Molecular Biology Reviews, 2006
SUMMARY The archaeal DNA replication machinery bears striking similarity to that of eukaryotes and is clearly distinct from the bacterial apparatus. In recent years, considerable advances have been made in understanding the biochemistry of the archaeal replication proteins.
