Summary: Enables chromatin binding activity. Involved in pre-replicative complex assembly involved in nuclear cell cycle DNA replication; regulation of DNA-templated DNA replication initiation; and ribosome biogenesis. Located in nucleoplasm. Part of nuclear pre-replicative complex and rixosome complex. Orthologous to human WDR18 (WD repeat domain 18). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

study identified the Rix1 complex members (Ipi1p-Ipi2p/Rix1-Ipi3p) as pre-replicative complex components and critical determinants of replication licensing and replication-initiation frequency
Title: The Rix1 (Ipi1p-2p-3p) complex is a critical determinant of DNA replication licensing independent of their roles in ribosome biogenesis.
