Crystal structure of the eukaryotic origin recognition complex. [PDF]
Initiation of cellular DNA replication is tightly controlled to sustain genomic integrity. In eukaryotes, the heterohexameric origin recognition complex (ORC) is essential for coordinating replication onset. Here we describe the crystal structure of Drosophila ORC at 3.5 Å resolution, showing that the 270 kilodalton initiator core complex comprises a ...

The origin recognition complex in human diseases. [PDF]
ORC (origin recognition complex) serves as the initiator for the assembly of the pre-RC (pre-replication complex) and the subsequent DNA replication. Together with many of its non-replication functions, ORC is a pivotal regulator of various cellular processes.

Assembly of the Human Origin Recognition Complex [PDF]
The six-subunit origin recognition complex (ORC) was originally identified in the yeast Saccharomyces cerevisiae. Yeast ORC binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors, such as Cdc6 and the Mcm proteins.

The origin recognition complex protein family [PDF]
Origin recognition complex (ORC) proteins were first discovered as a six-subunit assemblage in budding yeast that promotes the initiation of DNA replication. Orc1-5 appear to be present in all eukaryotes, and include both AAA+ and winged-helix motifs.

Chromatin replication involves the assembly and activity of the replisome within the nucleosomal landscape. At the core of the replisome is the Mcm2-7 complex (MCM), which is loaded onto DNA after binding to the Origin Recognition Complex (ORC). In yeast,

The remarkable gymnastics of ORC
As a cell prepares to divide, a molecular actor known as the Origin Recognition Complex makes intricate ATP-driven movements to recruit proteins required to duplicate DNA.

Structural insight into the assembly and conformational activation of human origin recognition complex. [PDF]
The function of the origin recognition complex (ORC) in DNA replication is highly conserved in recognizing and marking the initiation sites. The detailed molecular mechanisms by which human ORC is reconfigured into a state competent for origin ...

Mathematical modelling of whole chromosome replication [PDF]
All chromosomes must be completely replicated prior to cell division, a requirement that demands the activation of a sufficient number of appropriately distributed DNA replication origins.
