DESCRIPTION

Also known as UHRF2_HUMAN, UHRF2, NIRF, RNF107. E3 ubiquitin ligase that plays important roles in DNA methylation, histone modifications, cell cycle and DNA repair (PubMed:15178429, PubMed:29506131, PubMed:27743347, PubMed:23404503). Acts as a specific reader for 5-hydroxymethylcytosine (5hmC) and thereby recruits various substrates to these sites to ubiquitinate them (PubMed:27129234, PubMed:24813944). This activity also allows the maintenance of 5mC levels at specific genomic loci and regulates neuron-related gene expression (By similarity). Participates in cell cycle regulation by ubiquitinating cyclins CCND1 and CCNE1 and thereby inducing G1 arrest (PubMed:15178429, PubMed:15361834, PubMed:21952639). Ubiquitinates also PCNP leading to its degradation by the proteasome (PubMed:14741369, PubMed:12176013). Plays an active role in DNA damage repair by ubiquitinating p21/CDKN1A leading to its proteosomal degradation (PubMed:29923055). Promotes also DNA repair by acting as an interstrand cross-links (ICLs) sensor. Mechanistically, cooperates with UHRF1 to ensure recruitment of FANCD2 to ICLs, leading to FANCD2 monoubiquitination and subsequent activation (PubMed:30335751). Contributes to UV-induced DNA damage response by physically interacting with ATR in response to irradiation, thereby promoting ATR activation (PubMed:33848395). Homodimer; disulfide-linked. Binds methylated CpG containing oligonucleotides. Interacts with H3; the interaction has a preference for the 'Lys-9' trimethylated form of H3 (H3K9me3) (By similarity). Interacts with PCNP (PubMed:12176013, PubMed:14741369). Interacts with HDAC1 (PubMed:15361834). Interacts directly with CCNE1; the interaction ubiquitinates CCNE1 and appears independent of CCNE1 phosphorylation (PubMed:21952639). Interacts with CCND1; the interaction ubiquitinates CCND1 and appears independent of CCND1 phosphorylation (PubMed:21952639). Interacts with p53/TP53 and RB1 (PubMed:21952639). Interacts with UBE2I (PubMed:23404503). Interacts with ZNF618 (PubMed:27129234). Interacts with UHRF1 (PubMed:30335751). Interacts with FANCD2 (PubMed:30335751). Interacts with ATR (PubMed:33848395). Interacts with PCNA (PubMed:28951215).
