GINS2 (GINS Complex Subunit 2) is a Protein Coding gene. Among its related pathways are Cell Cycle, Mitotic and Telomere C-strand (Lagging Strand) Synthesis. The yeast heterotetrameric GINS complex is made up of Sld5, Psf1 , Psf2, and Psf3. The formation of this complex is essential for the initiation of DNA replication in yeast and Xenopus egg extracts.
