Acts as component of the Mcm2-7 complex (Mcm complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the Mcm2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity. Required for DNA replication and cell proliferation.

The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity; specifically the MCM2-MCM5 association is proposed to be reversible and to mediate a open ring conformation which may facilitate DNA loading. Once loaded onto DNA, double hexamers can slide on dsDNA in the absence of ATPase activity. Necessary for cell growth.

>PF11310 DUF3113: Protein of unknown function (DUF3113); InterPro: IPR021461 This entry is represented by Bacteriophage 92, Orf93
This model describes an uncharacterized domain of about 70 residues found exclusively in plants, generally toward the C-terminus of proteins of 200 to 350 amino acids in length. At least 14 such proteins are found in Arabidopsis thaliana. Other regions of these proteins tend to consist largely of low-complexity sequence.
>PF04844 Ovate: Transcriptional repressor, ovate; InterPro: IPR006458 This group of sequences contain an uncharacterised domain of about 70 residues found exclusively in plants, generally toward the C terminus of proteins of 200 to 350 amino acids in length
At least 14 such proteins are found in Arabidopsis thaliana (Mouse-ear cress). Other regions of these proteins tend to consist largely of low-complexity sequence. Function is not known.
All proteins in this family for which functions are known are components of a multiprotein complex used for targeting nucleotide excision repair to specific parts of the genome. In humans, Rad23 complexes with the XPC protein. This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University).
