ORC4 Antibody

1. Since the site of one of the missense mutations in the human ORC4 alleles is conserved between humans and yeast, we sought to determine in what way this single amino acid change affects the process of chromosome replication, by introducing the comparable mutation into yeast (orc4Y232C). PMID: 29036220
2. HsOrc4 could have a fundamental function in the process of initiation of replication by remodeling the structure of origin of replication using the energy of supercoiled DNA. PMID: 26124052
3. compared with homozygous missense mutations, compound heterozygous mutations appeared to have a more severe effect on phenotype, causing more severe growth retardation in ORC4 PMID: 22333897
4. identified three different mutations in the gene encoding ORC4, a component of the eukaryotic origin recognition complex, in five individuals with Meier-Gorlin syndrome PMID: 21358631
5. DNA binding activity of HsOrc4 depends on length and structure of DNA with triplex being the protein's preferred binding target. PMID: 19690980
6. Study using HCT116 haplo-insufficient cells and Orc2 hypomorphic cells demonstrates that the binding of human Ku to replication origins precedes that of Orc-3, -4, and -6 subunit binding. PMID: 15910003
7. describe 3 patients with B-cell lymphoproliferative disorders (2 with non-Hodgkin lymphoma and 1 with nonsecretory multiple myeloma) carrying a novel A286V mutation within ORC4L gene PMID: 20010161
8. Biochemical characterization of the mouse homolog PMID: 10460412
