General annotation (Comments)
| 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. Ref.8 |
| Catalytic activity | ATP + H2O = ADP + phosphate. |
| Subunit structure | 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). May interact with MCM10. Interacts with TIPIN. Interacts with CDT1. Interacts with MCMBP. Ref.8 Ref.9 Ref.11 Ref.13 Ref.14 Ref.22 |
| Subcellular location | Nucleus. Note: Binds to chromatin during G1 and detach from it during S phase. |
| Post-translational modification | O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner. Ref.21 |
| Polymorphism | Intronic variations in MCM6 upstream from the LCT gene are associated with adult-type hypolactasia [MIM:223100] leading to lactose intolerance, or with lactase persistance. Lactose intolerance is a normal physiological phenomenon caused by developmental down-regulation of lactase activity during childhood or early adulthood. A non-coding variation in MCM6 affects the transcriptional regulation of the LCT gene resulting in down-regulation of lactase activity. However, the majority of Northern Europeans and some African populations have the ability to maintain lactase activity and digest lactose throughout life (lactase persistence). |
| Miscellaneous | Early fractionation of eukaryotic MCM proteins yielded a variety of dimeric, trimeric and tetrameric complexes with unclear biological significance. Specifically a MCM467 subcomplex is shown to have in vitro helicase activity which is inhibited by the MCM2 subunit. The MCM2-7 hexamer is the proposed physiological active complex. |
| Sequence similarities | Belongs to the MCM family. Contains 1 MCM domain. |
