AbstractHuman UHRF1(ubiquitin-like PHD and RING finger 1) functions to maintain CpG DNA methylation patterns through DNA replication by co-localizing with the DNA methyltransferase DNMT1 at chromatin in mammals. Recent studies show that UHRF1 binds selectively to hemimethylated CpG via its conserved SRA (SET- and RING finger-associated) domain. However, the underlying molecular mechanism is not known. Here, we report a 1.95 Å resolution crystal structure of the SRA domain of human UHRF1. Using NMR structure-guided mutagenesis, electrophoretic mobility shift assay, and fluorescence anisotropy analysis, we determined key amino acid residues for methyl-DNA binding that are conserved in the SRA domain.
