The yeast heterotetrameric GINS complex is made up of Sld5
(GINS4; MIM 610611), Psf1 (GINS1; MIM 610608), Psf2, and Psf3
(GINS3; MIM 610610). The formation of this complex is essential for
the initiation of DNA replication in yeast and Xenopus egg extracts
(Ueno et al., 2005 [PubMed 16287864]). See GINS1 for additional
information about the GINS complex.
