DNA-binding is ATP-dependent. The specific DNA sequences that define origins of replication have not been identified yet. ORC is required to assemble the pre- replication complex necessary to initiate DNA replication. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3. Stabilizes LRWD1, by protecting it from ubiquitin- mediated proteasomal degradation. Also stabilizes ORC3. {ECO:0000269|PubMed:22427655, ECO:0000269|PubMed:22935713}. |ORC2| |condensed chromosome inner kinetochore| |origin recognition complex| |nuclear origin of replication recognition complex| |DNA replication origin binding| |heterochromatin| |DNA replication initiation| |nuclear chromosome, telomeric region| |G1/S transition of mitotic cell cycle| |DNA-dependent DNA replication| |cell cycle G1/S phase transition| |DNA replication| |mitotic cell cycle phase transition| |cell cycle phase transition| |centrosome| |mitotic cell cycle process| |mitotic cell cycle| |DNA metabolic process| |negative regulation of transcription by RNA polymerase II| |cell cycle process| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |cell cycle| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |cellular macromolecule biosynthetic process| |negative regulation of gene expression| |macromolecule biosynthetic process| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp518|RK-33 8μM R08 exp518]]|-1.71| No correlation found to any other genes in chemogenomics.
