Human Cytomegalovirus: detection of congenital and perinatal infection in Argentina [PDF]

open access: yes, 2004
BACKGROUND: Human cytomegalovirus (CMV) is one of the most commonly found agents of congenital infections. Primary maternal infection is associated with risk of symptomatic congenital diseases, and high morbidity is frequently associated with very low ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

MND1 and PSMC3IP control PARP inhibitor sensitivity in mitotic cells

open access: yesCell Reports, 2023
Summary: The PSMC3IP-MND1 heterodimer promotes meiotic D loop formation before DNA strand exchange. In genome-scale CRISPR-Cas9 mutagenesis and interference screens in mitotic cells, depletion of PSMC3IP or MND1 causes sensitivity to poly (ADP-Ribose ...

Reconstitution of recombination-associated DNA synthesis with human proteins. [PDF]

open access: yes, 2013
The repair of DNA breaks by homologous recombination is a high-fidelity process, necessary for the maintenance of genome integrity. Thus, DNA synthesis associated with recombinational repair must be largely error-free.

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

The Role OF DNA Polymerases in Carcinogenesis

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2016
Background and Objectives: The major role of various types of DNA polymerases is genome replication. However, DNA polymerases are also necessary to establish the accuracy, efficiency of replication, repairing process, and consequently decrease in ...

Tyrosines involved in the activity of φ29 single-stranded DNA binding protein.

open access: yesPLoS ONE, 2019
The genome of Bacillus subtilis phage ϕ29 consists of a linear double-stranded DNA with a terminal protein (TP) covalently linked to each 5' end (TP-DNA).

Polyamines stimulate DNA-directed DNA synthesis catalyzed by mammalian type C retroviral DNA polymerases.

open access: yesJournal of Biological Chemistry, 1981
In the presence of optimal concentrations of Mg2+, rates of activated (gapped) DNA-directed DNA synthesis by purified mammalian type C retroviral DNA polymerases are stimulated greater than 10-fold by the polyamines spermine and spermidine. Such stimulation was not observed using either similar concentrations of the polyamines cadaverine or putrescine ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...
