Overview
MCM4 a mini-chromosome maintenance protein, essential for the initiation of eukaryotic genome replication. The MCM hexameric protein complex is a key component of the pre-replication complex. The complex consisting of this protein and MCM2, 6 and 7 possesses DNA helicase activity. Phosphorylation by CDC2 reduces the DNA helicase activity and chromatin binding of the complex. Note: This description may include information from UniProtKB.
Protein type: DNA replication; EC 3.6.4.12
Cellular Component: nucleoplasm; MCM complex; nucleolus; nucleus
Molecular Function: ATP-dependent DNA helicase activity; protein binding; single-stranded DNA binding; ATP binding
Biological Process: DNA unwinding during replication; DNA replication initiation; DNA strand elongation during DNA replication; mitotic cell cycle; DNA replication; G1/S transition of mitotic cell cycle
Reference #:  P33991 (UniProtKB)
