The C terminal domain of CDC6 assumes a winged helix fold, with a five alpha-helical bundle (alpha15-alpha19) structure, backed on one side by three beta strands (beta6-beta8). 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].	Domain

This family represents the N-terminus (approximately 300 residues) of subunit 3 of the eukaryotic origin recognition complex (ORC). 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].	Domain
C	PF18137	Origin recognition complex winged helix C-terminal (ORC_WH_C)	Origin recognition complex winged helix C-terminal	This is the C-terminal winged-helix (WH) DNA-binding domain of the origin recognition complex present in Drosophila melanogaster. The WH domain is responsible for recognizing origin sequences [1].	Domain

ORC5 is a component of the origin recognition complex (ORC) that binds origins of replication. 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].	Domain
