KAP1 is an antiparallel dimer with a functional asymmetry

Didier Trono, Matteo Dal Peraro, Beat Fierz, Davide Demurtas, Louise Catherine Bryan, Maria Josefina Marcaida Lopez, Giulia Fonti, Pierre-Yves Joseph Laurent Helleboid, Alexandra Styliani Kalantzi

KAP1 (KRAB domain-associated protein 1) plays a fundamental role in regulating gene expression in mammalian cells by recruiting different transcription factors and altering the chromatin state. In doing so, KAP1 acts both as a platform for macromolecular i ...

Exploring on Protein-DNA interactions

Alexandra Styliani Kalantzi

A variety of DNA-binding proteins organizes the chromosomal DNA and regulates gene transcription, and DNA replication and recombination. In particular, for gene regulation there is a category of DNA-binding proteins, the transcription factors, which can de ...

Transcriptional regulatory logic of the diurnal cycle in the mouse liver

Bart Deplancke, Matteo Dal Peraro, Felix Naef, Guillaume Rey, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Sunil Kumar Raghav, Nouria Hernandez, Irina Krier, Alexandra Styliani Kalantzi

Many organisms exhibit temporal rhythms in gene expression that propel diurnal cycles in physiology. In the liver of mammals, these rhythms are controlled by transcription-translation feedback loops of the core circadian clock and by feeding-fasting cycles ...

NAR Breakthrough Article Crystal structure of Hop2-Mnd1 and mechanistic insights into its role in meiotic recombination

Matteo Dal Peraro, Alexandra Styliani Kalantzi

In meiotic DNA recombination, the Hop2-Mnd1 complex promotes Dmc1-mediated single-stranded DNA (ssDNA) invasion into homologous chromosomes to form a synaptic complex by a yet-unclear mechanism. Here, the crystal structure of Hop2-Mnd1 reveals that it form ...
