Nucleosome-directed replication origin licensing independent of a consensus DNA sequence
Most eukaryotes do not use a consensus DNA sequence as binding sites for the origin recognition complex (ORC) to initiate DNA replication, however budding yeast do. Here the authors show S. cerevisiae ORC can bind nucleosomes near nucleosome-free regions

The origin recognition complex: from simple origins to complex functions [PDF]
Eukaryotic DNA replication is an intricate process that requires the coordinate and tightly regulated action of numerous molecular machines. Eukaryotic cells must choose hundreds if not thousands of origins of replication and assemble multiple proteins or protein complexes at these sites. During S phase, these complexes are activated in a reproducible,

In the absence of ATPase activity, pre-RC formation is blocked prior to MCM2-7 hexamer dimerization [PDF]
The origin recognition complex (ORC) of Saccharomyces cerevisiae binds origin DNA and cooperates with Cdc6 and Cdt1 to load the replicative helicase MCM2–7 onto DNA. Helicase loading involves two MCM2–7 hexamers that assemble into a double hexamer around

Structural basis for origin recognition complex 1 protein-silence information regulator 1 protein interaction in epigenetic silencing [PDF]
The interaction between silence information regulator 1 protein (Sir1p) and origin recognition complex 1 protein (Orc1p), the largest subunit of the origin recognition complex, plays an important role in the establishment of transcriptional silencing at ...

RNA‐dependent recruitment of the origin recognition complex [PDF]
The origin recognition complex (ORC) has an important function in determining the initiation sites of DNA replication. In higher eukaryotes, ORC lacks sequence-specific DNA binding, and the mechanisms of ORC recruitment and origin determination are poorly understood.

Cdc6 ATPase activity regulates ORC center dot Cdc6 stability and the selection of specific DNA sequences as origins of DNA replication [PDF]
DNA replication, as with all macromolecular synthesis steps, is controlled in part at the level of initiation. Although the origin recognition complex ( ORC) binds to origins of DNA replication, it does not solely determine their location.

The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]
Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

The origin recognition complex is dispensable for endoreplication in Drosophila [PDF]
The origin recognition complex (ORC) is an essential component of the prereplication complex (pre-RC) in mitotic cell cycles. The role of ORC as a foundation to assemble the pre-RC is conserved from yeast to human. Furthermore, in metazoans ORC plays a key role in determining the timing of replication initiation and origin usage ...
