MCM2 (DNA Replication Licensing Factor MCM2, Minichromosome maintenance Protein 2 Homolog Nuclear Protein BM28, MCM2, BM28, CCNL1, CDCL1, KIAA0030)

The mini-chromosome maintenance (MCM) family of proteins, including MCM2, MCM3, MCM4 (Cdc21), MCM5 (Cdc46), MCM6 (Mis5) and MCM7 (Cdc47), are regulators of DNA replication that act to ensure replication occurs only once in the cell cycle. Expression of MCM proteins increases during cell growth, peaking at G1 to S phase. The MCM proteins each contain an ATPbinding motif, which is predicted to mediate ATP-dependent opening of doublestranded DNA. MCM proteins are regulated by E2F transcription factors, which induce MCM expression, and by protein kinases, which interact with MCM proteins to maintain...
