Humanizing the yeast origin recognition complex [PDF]
Nature Communications, 2021 In most model yeast species the Origin Recognition Complex (ORC) binds defined and species-specific base sequences while in humans what determines the binding appears to be more complex.

The dynamic nature of the human origin recognition complex revealed through five cryoEM structures [PDF]
eLife, 2020 Genome replication is initiated from specific origin sites established by dynamic events. The Origin Recognition Complex (ORC) is necessary for orchestrating the initiation process by binding to origin DNA, recruiting CDC6, and assembling the MCM ...

The Origin Recognition Complex: From Origin Selection to Replication Licensing in Yeast and Humans [PDF]
Biology, 2023 Understanding human DNA replication through the study of yeast has been an extremely fruitful journey. The minichromosome maintenance (MCM) 2–7 genes that encode the catalytic core of the eukaryotic replisome were initially identified through forward ...

Structural mechanism for replication origin binding and remodeling by a metazoan origin recognition complex and its co-loader Cdc6 [PDF]
Nature Communications, 2020 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 ...

Analysis of cilia dysfunction phenotypes in zebrafish embryos depleted of Origin recognition complex factors. [PDF]
Eur J Hum Genet, 2019 Meier–Gorlin syndrome (MGS) is a rare, congenital primordial microcephalic dwarfism disorder. MGS is caused by genetic variants of components of the origin recognition complex (ORC) consisting of ORC1–6 and the pre-replication complex, which together ...

Diverged composition and regulation of the Trypanosoma brucei origin recognition complex that mediates DNA replication initiation. [PDF]
Nucleic Acids Res, 2016 Initiation of DNA replication depends upon recognition of genomic sites, termed origins, by AAA+ ATPases. In prokaryotes a single factor binds each origin, whereas in eukaryotes this role is played by a six-protein origin recognition complex (ORC).
