The metazoan origin recognition complex [PDF]
Regulated initiation of DNA replication relies on the firing of initiator proteins that bind specifically to origin DNA. The discovery of the first eukaryotic initiator, the Saccharomyces cerevisiae Origin Recognition Complex (ORC) has allowed us to discern some aspects of how the onset of replication is regulated.

Origin recognition complex 6 overexpression promotes growth of glioma cells [PDF]
The discovery of novel oncotargets for glioma is of immense significance. We here explored the expression patterns, biological functions, and underlying mechanisms associated with ORC6 (origin recognition complex 6) in glioma.

Origin recognition complex binding to a metazoan replication origin [PDF]
The initiation of DNA replication in eukaryotic cells at the onset of S phase requires the origin recognition complex (ORC) [1]. This six-subunit complex, first isolated in Saccharomyces cerevisiae [2], is evolutionarily conserved [1]. ORC participates in the formation of the prereplicative complex [3], which is necessary to establish replication ...

Structural mechanism for replication origin binding and remodeling by a metazoan origin recognition complex and its co-loader Cdc6 [PDF]
The origin recognition complex (ORC) is essential for loading the Mcm2–7 replicative helicase onto DNA during DNA replication initiation. Here, the authors describe several cryo-electron microscopy structures of Drosophila ORC bound to DNA and its ...

Replication licensing regulated by a short linear motif within an intrinsically disordered region of origin recognition complex [PDF]
In eukaryotes, the origin recognition complex (ORC) faciliates the assembly of pre-replicative complex (pre-RC) at origin DNA for replication licensing.

Identification of ORC1/CDC6-interacting factors in Trypanosoma brucei reveals critical features of origin recognition complex architecture. [PDF]
DNA replication initiates by formation of a pre-replication complex on sequences termed origins. In eukaryotes, the pre-replication complex is composed of the Origin Recognition Complex (ORC), Cdc6 and the MCM replicative helicase in conjunction with ...

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 ...

Systemic analysis of the DNA replication regulator origin recognition complex in lung adenocarcinomas identifies prognostic and expression significance [PDF]
Background DNA replication alteration is a hallmark of patients with lung adenocarcinoma (LUAD) and is frequently observed in LUAD progression. Origin recognition complex (ORC) 1, ORC2, ORC3, ORC4, ORC5, and ORC6 form a replication–initiator complex to ...
