This accessory factor for DNA replication plays a role in accurately duplicating the genome in vivo. This domain folds into a helical extension that is linked to the beta-propeller domain (Pfam:PF12341) and protrudes from one face of the disk-shaped trimer formed by the protein. It is essential for binding of dynamic partner proteins, such as Pol alpha-primase [1-4].

The GINS complex is crucial for the establishment of DNA replication forks and replisome progression in eukaryotes. The crystal structure of the human GINS complex reveals a heterotetrameric assembly with a pseudo symmetrical layered structure. The complex consists of two heterodimers that create four subunit-subunit interfaces. The subunit structures of the heterodimers consist of two alternating domains, an alpha-helix-rich (A) domain Pfam:PF05916 and a beta-strand-rich (B) domain (this entry).

PF21128MCM4, winged helix domain (MCM4_WHD)MCM4, winged helix domainDNA replication licensing factor MCM4 is a component of the MCM2-MCM7 complex which consists of six sequence-related AAA+ type ATPases/helicases that form a heterohexameric ring essential for 'once per cell cycle' DNA replication initiation and elon ...DNA replication licensing factor MCM4 is a component of the MCM2-MCM7 complex which consists of six sequence-related AAA+ type ATPases/helicases that form a heterohexameric ring essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells [1-3]. This is the winged helix domain (WHD) found at the C-terminal of MCM4 [1-3]. Upon ssDNA binding the MCM5-WHD moves out of the central channel and becomes disordered, the MCM6-WHD moves backward and away from the channel, and the MCM4-WHD now partially occludes the channel opening. These changes enable CMG (Cdc45, Mcm2-7, GINS, the eukaryotic replicative helicase) to encircle dsDNA, and is consistent with reports that showed the MCM2-7 matures into two fully assembled CMGs on dsDNA before origin DNA unwinding occurs [3].
