UHRF1 (Q96T88) - Overview - Molecular Target Synopsis


UHRF1, E3 ubiquitin-protein ligase UHRF1
Enzyme Classification
UniProt Q96T88

Also Known as UHRF1_HUMAN, UHRF1, ICBP90, NP95, RNF106

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. Interacts with DNMT3A and DNMT3B (By similarity). Interacts with DNMT1; the interaction is direct. Interacts with USP7; leading to its deubiquitination. Interacts with histone H3. Interacts with HDAC1, but not with HDAC2. Interacts with UHRF1BP1. Interacts with PML. Interacts with EHMT2. Binds hemimethylated CpG containing oligonucleotides.
