Type: Homologous_superfamily
Description: This entry represents the ORC1-binding domain of Sir1. It has a complex fold, composed of an alpha hairpin, meander β-sheet and a five-stranded barrel of unusual topology. Sir1 interacts with the BAH domain of the Orc1 subunit of the origin recognition complex (ORC) resulting in the establishment of silent chromatin at HMR and HML in S.cerevisiae []. The amino acids from the ORC interaction region of Sir1 are presented on a conserved, convex surface that forms a complementary interface with the Orc1 BAH domain, critical for transcriptional silencing [].

Protein Domain
Type: Family
Description: The Origin Recognition Complex (ORC) is a six-subunit ATP-dependent DNA-binding complex encoded in yeast by ORC1-6 []. ORC is a central component for eukaryotic DNA replication, and binds chromatin at replication origins throughout the cell cycle []. ORC directs DNA replication throughout the genome and is required for its initiation [, , ]. ORC bound at replication origins serves as the foundation for assembly of the pre-replicative complex (pre-RC), which includes Cdc6, Tah11 (aka Cdt1), and the Mcm2-7 complex [, , ]. Pre-RC assembly during G1 is required for replication licensing of chromosomes prior to DNA synthesis during S phase [, , ]. Cell cycle-regulated phosphorylation of ORC2, ORC6, Cdc6, and MCM by the cyclin-dependent protein kinase Cdc28 regulates initiation of DNA replication, including blocking reinitiation in G2/M phase [, , , ]. In yeast, ORC also plays a role in the establishment of silencing at the mating-type loci Hidden MAT Left (HML) and Hidden MAT Right (HMR) [, , ]. ORC participates in the assembly of transcriptionally silent chromatin at HML and HMR by recruiting the Sir1 silencing protein to the HML and HMR silencers [, , ]. Both ORC1 and ORC5 bind ATP, although only ORC1 has ATPase activity []. The binding of ATP by ORC1 is required for ORC binding to DNA and is essential for cell viability []. The ATPase activity of ORC1 is involved in formation of the pre-RC [, , ]. ATP binding by ORC5 is crucial for the stability of ORC as a whole. Only the ORC1-5 subunits are required for origin binding; ORC6 is essential for maintenance of pre-RCs once formed []. Interactions within ORC suggest that ORC2-3-6 may form a core complex []. ORC homologues have been found in various eukaryotes, including fission yeast, insects, amphibians, and humans []. This group represents an origin recognition complex, subunit 4.
