(Submitter supplied) KRAB-zinc finger proteins (KZFPs) represent one of the largest families of DNA binding proteins in vertebrate genomes and appear to have evolved to silence transposable elements (TEs) including endogenous retroviruses through sequence-specific targeting of repressive chromatin states. However, one member, ZFP57, is required to maintain the post-fertilization DNA methylation memory of parental-origin at genomic imprints. more...

(Submitter supplied) Selective maintenance of genomic methylation imprints during pre-implantation development is required for parental origin-specific expression of imprinted genes. The Kruppel-like zinc finger protein ZFP57 acts as a factor necessary for maintaining the DNA methylation memory at multiple imprinting control regions (ICRs) in early mouse embryos and ES cells. Maternal-zygotic deletion of ZFP57 in mice presents a highly penetrant phenotype with no animals surviving to birth. more...

(Submitter supplied) The KZFP/KAP1 (KRAB zinc finger proteins/KRAB-associated protein 1) system plays a central role in the silencing of transposable elements (TEs) and the maintenance of parent-of-origin DNA methylation at imprinting control regions (ICRs) during the wave of genome-wide reprogramming that precedes implantation. In naïve murine embryonic stem cells (mESCs), the genome is maintained highly hypomethylated by a combination of active demethylation (operated by TET proteins) and lack of de novo methylation; in these cells, KAP1 is tethered by sequence-specific KZFPs to ICRs and TEs where it recruits histone and DNA methyltransferases to impose heterochromatin formation and DNA methylation. more...

(Submitter supplied) We previously reported a child with transient neonatal diabetes mellitus (TNDM), who upon molecular diagnosis was homozygous for a one base-pair deletion in ZFP57, inheriting the mutations from both heterozygous parents. Methylation profiling at diagnosis revealed severe hypomethylation at PLAGL1 and mosaic loss-of-methylation (LOM) at GRB10, NAP1L5 and GNAS-XL DMRs. Some years after the first child, a second sibling was born with a comparable clinical presentation. more...

(Submitter supplied) Bisulphite (BS) converted DNA from 2 paternal uniparental diploidies (pUPDs), one maternal (mUPD) and 5 control leukocytes samples were hybridized to the Infinium HumanMethylationEPIC BeadChip (Illumina), obtaining the BS DNA methylation profiles across approximately 850,000 CpGs. In addition, the 5 control leukocyte samples were also coverted using oxidative bisulphite (oxBS) treatment. The selective chemical oxidation of 5-hydroxymethylcytosine (5hmC) to 5-formylcytosine (5fC) and the deamination of the latter to uracil during the BS conversion allowed the quantification of independent 5-methylcytosine (5mC) and 5hmC methylation levels at every single CpG.

(Submitter supplied) ZFP57 is necessary for maintaining repressive epigenetic modifications at Imprinting control regions (ICRs). In mouse embryonic stem cells (ESCs), ZFP57 binds ICRs (ICRBS) and many other loci (non-ICRBS). To address the role of ZFP57 on all its target sites, we performed high-throughput and multi-locus analyses of inbred and hybrid mouse ESC lines carrying different gene knockouts. By using an allele-specific RNA-seq approach, we demonstrate that ZFP57 loss results in derepression of the imprinted allele of multiple genes in the imprinted clusters. more...

(Submitter supplied) ZFP57 interacts with the germline-derived differentially methylated regions (DMRs) of imprinted genes, and is required to maintain DMR methylation in mouse embryonic stem cells (ESCs). Although DNA methylation has a key role in maintaining genomic imprinting, several imprinted genes are controlled by different mechanisms, and a comprehensive study of the relationship between DMR methylation and imprinted gene expression is lacking. more...

(Submitter supplied) Encoded in the hundreds by the human genome, KRAB-containing zinc finger proteins (KRAB-ZFPs) constitute a rapidly evolving family of transcription factors with largely undefined functions. Here, by a combination of phylogenetic and genomic approaches, we retrace the evolutionary history of KRAB-ZFP genes and define the genomic targets of their human products. Through in silico analysis of 207 vertebrate genomes and chromatin immunoprecipitation / deep sequencing characterization of 257 human KRAB-ZFPs, we identify the root of the family in an early Devonian ancestor of tetrapods, describe its diversity amongst these species, and reveal that the majority of its human members primarily recognize transposable elements. more...

(Submitter supplied) ZFP445/ZNF445 collaborates with ZFP57 to control genomic imprinting in vivo in mouse and in human embryonic stem cells. We determined that ZNF445/ZFP445, a KZFP that can be traced back to marsupials, binds human and murine ICRs, and together with ZFP57 correctly maintains all but one murine ICR in vivo. Furthermore, the early embryonic expression of human ZNF445 and its intolerance to loss of function mutations in the population suggest a critical role in human development.

(Submitter supplied) The tetrapod-restricted KRAB-containing zinc finger proteins (KRAB-ZFPs) are essential early embryonic controllers of transposable elements (TEs), which they repress via their cofactor KAP1 and associated effectors through histone and DNA methylation, a process thought to result in irreversible silencing. Using a target-centered functional screen, we matched several murine TEs with their cognate KRAB-ZFP. more...
