研究背景

功能:

Multidomain protein that acts as a key epigenetic regulator by bridging DNA methylation and chromatin modification. Specifically recognizes and binds hemimethylated DNA at replication forks via its YDG domain and recruits DNMT1 methyltransferase to ensure faithful propagation of the DNA methylation patterns through DNA replication. In addition to its role in maintenance of DNA methylation, also plays a key role in chromatin modification: through its tudor-like regions and PHD-type zinc fingers, specifically recognizes and binds histone H3 trimethylated at 'Lys-9' (H3K9me3) and unmethylated at 'Arg-2' (H3R2me0), respectively, and recruits chromatin proteins. Enriched in pericentric heterochromatin where it recruits different chromatin modifiers required for this chromatin replication. Also localizes to euchromatic regions where it negatively regulates transcription possibly by impacting DNA methylation and histone modifications. Has E3 ubiquitin-protein ligase activity by mediating the ubiquitination of target proteins such as histone H3 and PML. It is still unclear how E3 ubiquitin-protein ligase activity is related to its role in chromatin in vivo. May be involved in DNA repair.

翻译修饰:

Phosphorylation at Ser-298 of the linker region decreases the binding to H3K9me3. Phosphorylation at Ser-639 by CDK1 during M phase impairs interaction with USP7, preventing deubiquitination and leading to degradation by the proteasome.

Ubiquitinated; which leads to proteasomal degradation. Autoubiquitinated; interaction with USP7 leads to deubiquitination and prevents degradation. Ubiquitination and degradation takes place during M phase, when phosphorylation at Ser-639 prevents interaction with USP7 and subsequent deubiquitination. Polyubiquitination may be stimulated by DNA damage.

细胞定位:

Nucleus.
Note: Localizes to replication foci. Enriched in pericentric heterochromatin. Also localizes to euchromatic regions.

蛋白家族:

The tudor-like regions specifically recognize and bind histone H3 unmethylated at 'Arg-2' (H3R2me0), while the PHD-type zinc finger specifically recognizes and binds histone H3 trimethylated at 'Lys-9' (H3K9me3). The tudor-like regions simultaneously recognizes H3K9me3 through a conserved aromatic cage in the first tudor-like subdomain and unmodified H3K4 (H3K4me0) within a groove between the tandem subdomains (PubMed:21489993, PubMed:21777816 and PubMed:22100450). The linker region plays a role in the formation of a histone H3-binding hole between the reader modules formed by the tudor-like regions and the PHD-type zinc finger by making extended contacts with the tandem tudor-like regions (PubMed:22837395).

The YDG domain (also named SRA domain) specifically recognizes and binds hemimethylated DNA at replication forks (DNA that is only methylated on the mother strand of replicating DNA) (PubMed:17673620). It contains a binding pocket that accommodates the 5-methylcytosine that is flipped out of the duplex DNA. 2 specialized loops reach through the resulting gap in the DNA from both the major and the minor grooves to read the other 3 bases of the CpG duplex. The major groove loop confers both specificity for the CpG dinucleotide and discrimination against methylation of deoxycytidine of the complementary strand (PubMed:18772889). The YDG domain also recognizes and binds 5-hydroxymethylcytosine (5hmC) (PubMed:21731699).

The RING finger is required for ubiquitin ligase activity.
