ID:MCM5_HUMAN DESCRIPTION: RecName: Full=DNA replication licensing factor MCM5; EC=3.6.4.12; AltName: Full=CDC46 homolog; AltName: Full=P1-CDC46; FUNCTION: 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 (By similarity). Interacts with MCMBP. CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate. SUBUNIT: Component of the MCM2-7 complex. The complex forms a toroidal hexameric ring with the proposed subunit order MCM2-MCM6- MCM4-MCM7-MCM3-MCM5 (By simililarity). INTERACTION: P62805:HIST2H4B; NbExp=2; IntAct=EBI-359410, EBI-302023; P49736:MCM2; NbExp=4; IntAct=EBI-359410, EBI-374819; P25205:MCM3; NbExp=3; IntAct=EBI-359410, EBI-355153; SUBCELLULAR LOCATION: Nucleus. MISCELLANEOUS: Early fractionation of eukaryotic MCM proteins yielded a variety of dimeric, trimeric and tetrameric complexes with unclear biological significance. The MCM2-7 hexamer is the proposed physiological active complex. SIMILARITY: Belongs to the MCM family. SIMILARITY: Contains 1 MCM domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
