Didier Trono, Priscilla Turelli, Julien Léonard Duc, Jonas Caspar De Tribolet-Hardy, Alexandra Iouranova, Michaël Imbeault, Alexandre Coudray, Tamara Rossy, Alexandre Louis André Persat, Delphine Yvette L Grun

Background Transposable element-embedded regulatory sequences (TEeRS) and their KRAB-containing zinc finger protein (KZFP) controllers are increasingly recognized as modulators of gene expression. We aim to characterize the contribution of this system to g ...

ZNF445 is a primary regulator of genomic imprinting

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Michaël Imbeault, Andrea Coluccio, Evaristo Jose Planet Letschert, Christian Axel Wandall Thorball

Genomic imprinting is an epigenetic process regulated by germline-derived DNA methylation, causing parental origin-specific monoallelic gene expression. Zinc finger protein 57 (ZFP57) is critical for maintenance of this epigenetic memory during post-fertil ...

The interactome of KRAB zinc finger proteins reveals the evolutionary history of their functional diversification

Didier Trono, Priscilla Turelli, Ruedi Aebersold, Julien Léonard Duc, Michaël Imbeault, Cécile Piot, Andrea Coluccio, Pierre-Yves Joseph Laurent Helleboid, Christian Axel Wandall Thorball, Julien Paul André Pontis

Krüppel‐associated box (KRAB)‐containing zinc finger proteins (KZFPs) are encoded in the hundreds by the genomes of higher vertebrates, and many act with the heterochromatin‐inducing KAP1 as repressors of transposable elements (TEs) during early embryogene ...

ZFP30 promotes adipogenesis through the KAP1-mediated activation of a retrotransposon-derived Pparg2 enhancer

Carine Delattre-Gubelmann, Didier Trono, Julien Léonard Duc, Bart Deplancke, Sunil Kumar Raghav, Marco Cassano, Michaël Imbeault, Petra Catalina Schwalie, Suk Min Jang, Riccardo Dainese, Julie Marie Russeil, Wanze Chen, Evgeniia Pankevich

Krüppel-associated box zinc finger proteins (KZFPs) constitute the largest family of mammalian transcription factors, but most remain completely uncharacterized. While initially proposed to primarily repress transposable elements, recent reports have revea ...

KRAB-ZFPs and transposable elements rewire early human embryonic development transcriptional networks

KRAB zinc-finger proteins contribute to the evolution of gene regulatory networks

Didier Trono, Michaël Imbeault, Pierre-Yves Joseph Laurent Helleboid

The human genome encodes some 350 Kruppel-associated box (KRAB) domain-containing zinc-finger proteins (KZFPs), the products of a rapidly evolving gene family that has been traced back to early tetrapods(1,2). The function of most KZFPs is unknown, but a f ...

The mouse genome displays highly dynamic populations of KRAB-zinc finger protein genes and related genetic units

Didier Trono, Annamaria Kauzlaric, Julien Léonard Duc, Gabriela Ecco, Marco Cassano, Michaël Imbeault

KRAB-containing poly-zinc finger proteins (KZFPs) constitute the largest family of transcription factors encoded by mammalian genomes, and growing evidence indicates that they fulfill functions critical to both embryonic development and maintenance of adul ...

KRAB zinc finger proteins

Didier Trono, Gabriela Ecco, Michaël Imbeault

Kruppel-associated box domain zinc finger proteins (KRAB-ZFPs) are the largest family of transcriptional regulators in higher vertebrates. Characterized by an N-terminal KRAB domain and a C-terminal array of DNA-binding zinc fingers, they participate, toge ...

SMiLE-seq identifies binding motifs of single and dimeric transcription factors

Philipp Bucher, Didier Trono, Giovanna Ambrosini, Bart Deplancke, Romain Fernand Pietro Groux, Alina Isakova, Pernille Yde Rainer, Michaël Imbeault, Riccardo Dainese, Daniel Alpern

Resolving the DNA-binding specificities of transcription factors (TFs) is of critical value for understanding gene regulation. Here, we present a novel, semiautomated protein-DNA interaction characterization technology, selective microfluidics-based ligand ...

A map of human PRDM9 binding provides evidence for novel behaviors of PRDM9 and other zinc-finger proteins in meiosis

Michaël Imbeault

PRDM9 binding localizes almost all meiotic recombination sites in humans and mice. However, most PRDM9-bound loci do not become recombination hotspots. To explore factors that affect binding and subsequent recombination outcomes, we mapped human PRDM9 bind ...

Transposable Elements and Their KRAB-ZFP Controllers Regulate Gene Expression in Adult Tissues

Didier Trono, Priscilla Turelli, Annamaria Kauzlaric, Julien Léonard Duc, Helen Mary Rowe, Sandra Eloise Kjeldsen, Gabriela Ecco, Marco Cassano, Michaël Imbeault, Andrea Coluccio

KRAB-containing zinc finger proteins (KRAB-ZFPs) are early embryonic controllers of transposable elements (TEs), which they repress with their cofactor KAP1 through histone and DNA methylation, a process thought to result in irreversible silencing. Using a ...

Molecular Criteria for Defining the Naive Human Pluripotent State

Didier Trono, Julien Léonard Duc, Marc Samuel Friedli, Alexandra Iouranova, Michaël Imbeault, Evaristo Jose Planet Letschert, Julien Paul André Pontis, Haoyi Wang

Recent studies have aimed to convert cultured human pluripotent cells to a naive state, but it remains unclear to what extent the resulting cells recapitulate in vivo naive pluripotency. Here we propose a set of molecular criteria for evaluating the naive ...

As Time Goes by: KRABs Evolve to KAP Endogenous Retroelements

Didier Trono, Michaël Imbeault

Retroelements, constituting about 50% of the human genome, both contribute to its evolution and threaten its integrity and are thus silenced during development. Jacobs et al. (2014) identify sequence-specific KRAB-ZNF proteins that repress subsets of L1 an ...
