HMDB Protein ID HMDBP11816
Secondary Accession Numbers None
Name DNA replication licensing factor MCM2
  1. Minichromosome maintenance protein 2 homolog
  2. Nuclear protein BM28
Gene Name MCM2
Protein Type Unknown
Biological Properties
General Function Not Available
Specific 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. Required for the entry in S phase and for cell division.
