In molecular biology ORC or origin recognition complex is a multi-subunit DNA binding complex (6 subunits) that binds in all eukaryotes 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 genes. ORC is a central component for eukaryotic DNA replication and binds chromatin at replication origins throughout the cell cycle. ORC directs DNA replication throughout the genome and is required for its initiation.
