ORC1

origin recognition complex subunit 1, L000003162, YML065W
Largest subunit of the origin recognition complex; involved in directing DNA replication by binding to replication origins; also involved in transcriptional silencing; exhibits ATPase activity; ORC1 has a paralog, SIR3, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

MCM7

CDC47, MCM DNA helicase complex subunit MCM7, L000002760, YBR202W
Component of the Mcm2-7 hexameric helicase complex; MCM2-7 primes origins of DNA replication in G1 and becomes an active ATP-dependent helicase that promotes DNA melting and elongation in S-phase; forms an Mcm4p-6p-7p subcomplex
Saccharomyces cerevisiae (S288c)

Multiple Cdt1 molecules act at each origin to load replication-competent Mcm2-7 helicases.

Takara TJ, Bell SP

Eukaryotic origins of replication are selected by loading a head-to-head double hexamer of the Mcm2-7 replicative helicase around origin DNA. Cdt1 plays an essential but transient role during this event; however, its mechanism of action is unknown. Through analysis of Cdt1 mutations, we demonstrate that Cdt1 performs multiple functions during helicase loading. The C-terminus of Cdt1 binds Mcm2-7, and this ... [more]
