WebThe origin recognition complex (ORC), a heteromeric six-subunit protein, is a central component for eukaryotic DNA replication. The ORC binds to DNA at replication origin sites in an ATP-dependent manner and serves as a scaffold for the assembly of other key initiation factors. Sequence rules for ORC-DNA binding appear to vary widely. WebThe ORC1 gene provides instructions for making a protein that is important in the copying of a cell's DNA before the cell divides (a process known as DNA replication). The protein …

In molecular biology, origin recognition complex (ORC) is a multi-subunit DNA binding complex (6 subunits) that binds in all eukaryotes and archaea in an ATP-dependent manner to origins of replication. The subunits of this complex are encoded by the ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6 … See more The following proteins are present in the ORC: Archaea feature a simplified version of the ORC, Mcm, and as a consequence the combined pre-RC. Instead of using six different mcm … See more Budding yeast Autonomously Replicating Sequences (ARS), first discovered in budding yeast, are integral to the … See more Although the ORC is composed of six discrete subunits, only one of these has been found to be significant - ORC1.
