(Submitter supplied) We have shown that many mouse KRAB-ZFPs target retrotransposons which are generally marked by H3K9me3 and KAP1 in ES cells. To test whether these KRAB-ZFPs are require to establish and maintain repressive chromatin marks at these elements, we performed ChIP-seq with antibodies against KAP1 (2 KRAB-ZFP cluster KOs) and H3K9me3 (5 KRAB-ZFP cluster KOs). We show that KRAB-ZFP targeted retrotransposons show reduced KAP1 binding and H3K9me3 in these KO ES cells. more...

(Submitter supplied) We report a retrotransposon-specific loss of CpG methylation in chromosome 4 KRAB-ZFP cluster (Chr4-cl) KO ES cells that are cultivated in conditions that induce DNA hypomethylation. The retrotransposon groups with the strongest DNA methylation loss are the main targets of the KRAB-ZFPs within the deleted gene cluster indicating that these KRAB-ZFPs prevent complete DNA demethylation at retrotransposons during global DNA demethylation.

(Submitter supplied) Mammalian genomes encode several hundred Krüppel-associated box zinc finger proteins (KRAB-ZFPs) that bind DNA in a sequence-specific manner through tandem arrays of C2H2-type zinc fingers and repress transcription via KRAB-dependent recruitment of the silencing cofactor KAP1. The KRAB-ZFP family rapidly amplified and diversified in mammals by segmental gene duplications, mutations, and zinc finger rearrangements likely in response to continued transposable element invasions, but the biological functions and in vivo requirement of these proteins has gone largely unexplored. more...

(Submitter supplied) Genetic deletion of a large KRAB-ZFP gene cluster on chromosome 4 (Chr4-cl) leads to transcriptional reactivation of retrotransposons (mainly ETn elements) in ES cells. We therefore wanted to test whether ETn elements retrotranspose in Chr4-cl KO mice at higher frequency. For this we purified genomic DNA from WT and KO mice, enriched gDNA libraries using ETn capture probes and sequenced those libraries as paire-end reads. more...

(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...

(Submitter supplied) We compared the binding patterns in embryonic stem cells of KAP1 and KRAB Zinc Finger (KZNF) proteins as well as H3K4me3 DNA under several conditions. Native human stem cells. Mouse stem cells containing a transchromosomic copy of human chromosome 11, with and without the introduction of plasmids containing KRAB Zinc Finger sequences. We show that certain KZNFs are responsible for the repression of certain retrotransposons in embryonic stem cells, preventing their spread across the genome.

(Submitter supplied) Transposable element (TE) invasions have shaped vertebrate genomes over the course of evolution. They have contributed an extra layer of species-specific gene regulation by providing novel transcription factor binding sites. In humans, SVA elements are one of three still active TE families, and approximately 2800 SVA insertions exist in the human genome, half of which are human-specific. TEs are often silenced by KRAB zinc finger (KZNF) proteins recruiting co-repressor proteins that establish a repressive chromatin state. more...

(Submitter supplied) Krüppel-associated box (KRAB) domain-containing zinc finger proteins (KZFPs) are one of the largest groups of transcription factors encoded by tetrapods, with 378 members in human alone. KZFP genes are often grouped in clusters reflecting amplification by gene and segment duplication since the gene family first emerged more than 400 million years ago. Previous work has revealed that many KZFPs recognize transposable element (TE)-embedded sequences as genomic targets, and that KZFPs facilitate the co-option of the regulatory potential of TEs for the benefit of the host. more...

(Submitter supplied) Kruppel-associated box (KRAB)-containing zinc-finger proteins (KZFPs) represent the largest family of transcription factors encoded by higher vertebrates. Together with their heterochromatin-inducing cofactor KAP1, many act as repressors of endogenous retroelements (EREs) during early embryonic genome reprogramming, yet their widespread expression in adult tissues and enrichment at other genetic loci indicate additional roles. more...

(Submitter supplied) Mobile elements are important evolutionary forces that challenge genomic integrity. Long interspersed element-1 (L1, also known as LINE-1) is the only autonomous transposon still active in the human genome. It displays an unusual pattern of evolution, with at any given time a single active L1 lineage amplifying to thousands of copies before getting replaced by a new lineage likely under pressure of host restriction factors, which act notably by silencing L1 expression during early embryogenesis. more...
