Origin recognition complex (ORC) is composed of six subunits that are essential for cell viability. They collectively bind to the autonomously replicating sequence (ARS) in a sequence-specific manner and lead to the chromatin loading of other replication factors that are essential for initiation of DNA replication [1]. This domain is predicted to contain an AAA+ fold but lack the residues important for ATP hydrolysis, thus, it is called AAA+ like [2].

ORC is required to assemble the pre-replication complex necessary to initiate DNA replication. This is the lid domain, which with the N-terminal RecA-fold domain, constitutes the well-known AAA+ domain [1].

It has been shown that this domain acts as a DNA-localisation factor, however its exact function is, as yet, unknown. Putative functions include: (1) mediation of protein-protein interactions and (2) regulation of nucleotide binding and hydrolysis. Mutagenesis studies have shown that this domain is essential for appropriate Cdc6 activity [1].
