| Post Translational Modifications | Ubiquitinated.undergoes 'Lys-48'-linked polyubiquitination leading to proteasomal degradation. Ubiquitination occurs within the WD repeats at the end of the G1 phase. Ubiquitination may be catalyzed by the CUL4-DDB1 E3 ubiquitin-protein ligase complex and other E3 ligases. |
| 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, H3K27me3 and H4K20me3 in a cooperative manner with DNA methylation. Required for silencing of major satellite repeats. May be important ORC2, ORC3 and ORC4 stability. |
