The protein encoded by this gene is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are involved in the initiation of eukaryotic genome replication. The hexameric protein complex formed by MCM proteins is a key component of the pre-replication complex (pre_RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication related proteins. This protein forms a complex with MCM4 , 6 , and 7 , and has been shown to regulate the helicase activity of the complex. This protein is phosphorylated , and thus regulated by , protein kinases CDC2 and CDC7. Multiple alternatively spliced transcript variants have been found , but the full-length nature of some variants has not been defined. [provided by RefSeq , Oct 2012] ,
