Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

N-terminal 6xHis-tagged
產品提供形式：

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點詳情

功能：

Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent. The 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.
基因功能參考文獻：
1. The opposing effects of ORC1 (represor) and CDC6 (gene activator) in controlling the level of Cyclin E ensures genome stability and a mechanism for linking directly DNA replication and cell division commitment. PMID: 27458800
2. The authors have discovered that human cell lines in culture proliferate with intact chromosomal origins of replication after disruption of both alleles of ORC2 or of the ATPase subunit, ORC1. PMID: 27906128
3. Orc1 acts as a nucleating center for origin recognition complex assembly and then pre-replication complex assembly by binding to mitotic chromosomes, followed by gradual removal from chromatin during the G1 phase. PMID: 25784553
4. ORC1 harbors a G-rich RNA/ssDNA-binding domain, which may be involved in the preferential binding to G-quadruplex-formable RNA/DNA by ORC. Structure modeling predicts the structural similarity between the G-rich RNA/ssDNA-binding domain of ORC1 and part of mammalian DNA methyltransferase 1. PMID: 24003239
5. ORC1 associated with transcription start sites of coding or noncoding RNAs. Transcription levels at the ORC1 sites directly correlated with replication timing. PMID: 23187890
6. results identify the BAH domain as a novel methyl-lysine-binding module, thereby establishing the first direct link between histone methylation and the metazoan DNA replication machinery, and defining a pivotal aetiological role for the canonical H4K20me2 mark, via ORC1, in primordial dwarfism PMID: 22398447
7. Orc1 harbors a PACT centrosome-targeting domain and a separate domain that differentially inhibits the protein kinase activities of Cyclin E-CDK2 and Cyclin A-CDK2 PMID: 22855792
8. Data show that purified Epstein-Barr nuclear antigen 1 EBNA1 recruits purified Human Orc1 and Cdc6 onto replication origin oriP. PMID: 22589552
9. A lethal phenotype was seen in four individuals with compound heterozygous ORC1 mutations PMID: 22333897
10. As cells moved through the cell cycle, the local-ization of ORC1 shifted, suggesting changes in thelocalization of ORC-bound origin sequences. PMID: 22045277
11. Mutations in ORC1, encoding a subunit of the origin recognition complex, cause microcephalic primordial dwarfism resembling Meier-Gorlin syndrome. These mutations disrupt ORC1 functions including pre-replicative complex formation and origin activation. PMID: 21358633
12. Data show that Orc1 specifically binds hypo-phosphorylated Rb and that this interaction is competitive with the binding of Rb to E2F1. PMID: 21085491
13. in human cancer cells, RBX1 silencing causes the accumulation of DNA replication licensing proteins CDT1 and ORC1, leading to DNA double-strand breaks, DDR, G(2) arrest, and, eventually, aneuploidy PMID: 21115485
14. a component of the origin recognition complex (ORC) that functions in DNA replication PMID: 11716535
15. ORC2 physically interacts with ORC1 on non-chromatin nuclear structures PMID: 11779870
16. Data suggest that hOrc1p is targeted for destruction by an SCF-Skp2 complex during S phase. PMID: 11931757
17. ORC1 regulates the status of the ORC complex in human nuclei by tethering ORCs 2-5 to nuclear structures PMID: 12909626
18. the ORC1 cycle in human cells is highly linked with cell cycle progression, allowing the initiation of replication to be coordinated with the cell cycle and preventing origins from refiring PMID: 12909627
19. The precise nucleotide of binding for ORC1 was identified near the start sites for leading-strand DNA synthesis. PMID: 12912926
20. HP1 has a role in the recruitment but not in the stable association of Orc1p with heterochromatin PMID: 15454574
21. BAH domain in human Orc1 facilitates its ability to activate replication origins in vivo by promoting association of ORC with chromatin. PMID: 17066079
22. Interacts with TRF2 to achieve stable binding in pre-replication complex assembly at telomeres. These data suggest that ORC might be involved in telomere homeostasis in human cells. PMID: 18761675
23. data suggest that Orc1 is a regulator of centriole and centrosome reduplication as well as the initiation of DNA replication PMID: 19197067
