Diversity of eukaryotic DNA replication origins revealed by genome-wide analysis of chromatin structure. [PDF]

open access: yesPLoS Genetics, 2010
Eukaryotic DNA replication origins differ both in their efficiency and in the characteristic time during S phase when they become active. The biological basis for these differences remains unknown, but they could be a consequence of chromatin structure ...

Abnormally proximal aortic origin of the brachiocephalic artery: Surgical implications

open access: yesAnnals of Pediatric Cardiology, 2022
Abnormal proximal aortic origin of the brachiocephalic artery is a very rare condition. It can occur in isolation or associated with complex congenital heart disease affecting the right ventricular outflow tract. Its recognition carries relevant surgical

Simian virus 40 DNA replication in vitro: identification of multiple stages of initiation [PDF]

open access: yes, 1989
A cell-free DNA replication system dependent upon five purified cellular proteins, one crude cellular fraction, and the simian virus 40 (SV40)-encoded large tumor antigen (T antigen) initiated and completed replication of plasmids containing the SV40 ...

The preRC protein ORCA organizes heterochromatin by assembling histone H3 lysine 9 methyltransferases on chromatin

open access: yeseLife, 2015
Heterochromatic domains are enriched with repressive histone marks, including histone H3 lysine 9 methylation, written by lysine methyltransferases (KMTs).

DNA replication origins retain mobile licensing proteins

open access: yesNature Communications, 2021
Eukaryotic DNA replication is regulated to ensure copying of the genome (only) once per cell cycle. Here the authors, using optical trapping and confocal microscopy, demonstrate the dynamics of the origin recognition complex and subsequent intermediates ...

A Distinct Mechanism to Achieve Efficient Signal Recognition Particle (SRP)-SRP Receptor Interaction by the Chloroplast SRP Pathway [PDF]

open access: yes, 2009
Cotranslational protein targeting by the signal recognition particle (SRP) requires the SRP RNA, which accelerates the interaction between the SRP and SRP receptor 200-fold.
