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 ...

The origin recognition complex: a biochemical and structural view. [PDF]
The origin recognition complex (ORC) was first discovered in the baker's yeast in 1992. Identification of ORC opened up a path for subsequent molecular level investigations on how eukaryotic cells initiate and control genome duplication each cell cycle ...

An Orc1 initiator-specific motif (ISM)-related region limits ORC–ssDNA binding and promotes replication origin specificity in budding yeast [PDF]
Single-stranded DNA (ssDNA) is an essential intermediate of genome duplication but can also arise in the genome, including at highly transcribed loci. Although the origin recognition complex (ORC), a eukaryotic replication initiator, has been reported to

A Drosophila homolog of the yeast origin recognition complex
Genes from Drosophila melanogaster have been identified that encode proteins homologous to Orc2p and Orc5p of the Saccharomyces cerevisiae origin recognition complex (ORC). The abundance of the Drosophila Orc2p homolog DmORC2 is developmentally regulated
