GINS1 (GINS Complex Subunit 1) is a Protein Coding gene. Diseases associated with GINS1 include Retinitis Pigmentosa 4, Autosomal Dominant Or Recessive. 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 (GINS4; MIM 610611), Psf1, Psf2 (GINS2; MIM 610609), and Psf3 (GINS3; MIM 610610). The formation of the GINS complex is essential for the initiation of DNA replication in yeast and Xenopus egg extracts .
