| Function |
Required for G1/S transition. Recruits and stabilizes the origin recognition complex (ORC) onto chromatin during G1 to establish pre-replication complex (preRC) and to heterochromatic sites in post-replicated cells. Binds a combination of DNA and histone methylation repressive marks on heterochromatin. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3 in a cooperative manner with DNA methylation. Required for silencing of major satellite repeats. May be important ORC2, ORC3 and ORC4 stability. {ECO:0000269|PubMed:20850016, ECO:0000269|PubMed:20932478, ECO:0000269|PubMed:21029866, ECO:0000269|PubMed:22427655, ECO:0000269|PubMed:22645314}.

| Subcellular Location |
Nucleus. Chromosome, centromere. Chromosome, telomere. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000250}. Note=Localizes to heterochromatin during G1 phase. Restricted to centromeres or telomeres as cells progress though S phase. When cells enter mitosis, relocalizes to centromeres. Recruitment to pericentric heterochromatin largely depends on the presence of H3K9me3.
|
| Tissue Specificity |
Testis-specific. Drastically down-regulated in testis from patients with Sertoli cell-only syndrome (SCOS). {ECO:0000269|PubMed:17074343}.
