Description

GINS is a key component of eukaryotic replicative forks. It is part of the CMG (Cdc45-MCM-GINS) complex, the eukaryotic replicative helicase that unwinds double-stranded DNA at replication forks [PMID: 23412083]. Beside its role as a key component of the CMG complex, GINS mediates a interactions with many replication factors [PMID: 22918584, PMID: 20070258].

GINS is composed of four subunits: Sld5, Psf1, Psf2, and Psf3 [PMID: 23412083]. The four subunits are structurally related and are likely to derive from a single protein. They share a common fold made up of an alpha-helical A domain and a beta rich B domain. Sld5 and Psf1 possess the A domain at the N terminus and the B domain at the C terminus, whereas these two domains are swapped in Psf2 and Psf3 [PMID: 28071757]. All subunits are essential for DNA replication.

This family of proteins represents the Sld5 subunit.
