The HP1 box of KAP1 organizes HP1α for silencing of endogenous retroviral elements in embryonic stem cells

Matteo Dal Peraro, Rudolf Hovius, Beat Fierz, Maria Josefina Marcaida Lopez

Repression of endogenous retroviral elements (ERVs) is facilitated by KAP1 (KRAB-associated protein 1)-containing complexes, however the underlying mechanism remains unclear. Here, we show that binding of KAP1 to the major component of the heterochromatin ...

A covalently linked probe to monitor local membrane properties surrounding plasma membrane proteins

Rudolf Hovius, Luc Reymond

We present a method probing the local membrane environment surrounding membrane proteins in the plasma membrane by linking a solvatochromic dye to the target, and provide evidence for lipid-based sorting. The insulin receptor environment changed upon insul ...

International Union of Basic and Clinical Pharmacology. CX. Classification of Receptors for 5-hydroxytryptamine; Pharmacology and Function

Horst Vogel, Rudolf Hovius

5 HT receptors expressed throughout the human body are targets for established therapeutics and various drugs in development. Their diversity of structure and function reflects the important role 5-HT receptors play in physiologic and pathophysiological pr ...

Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

Rudolf Hovius, Beat Fierz

The inner nuclear membrane is functionalized by diverse transmembrane proteins that associate with nuclear lamins and/or chromatin. When cells enter mitosis, membrane-chromatin contacts must be broken to allow for proper chromosome segregation; yet how thi ...

Structural mechanism of cGAS inhibition by the nucleosome

Rudolf Hovius, Beat Fierz, Andrea Ablasser, Baptiste Claude André Guey, Alexiane Clara Decout, Pauline Ambre Melenec, Simone Cavadini, Kristina Makasheva, Sélène-Véronique Glück

The DNA sensor cGAS initiates innate immune responses following microbial infection, cellular stress, and cancer1. Upon activation by double-stranded DNA, cytosolic cGAS produces 2’3’ cyclic GMP-AMP and triggers inflammatory cytokine and type I interferon ...

Chromatin Fiber Invasion and Nucleosome Displacement by the Rap1 Transcription Factor

Rudolf Hovius, Beat Fierz, Iuliia Boichenko, Maxime Nicolas Mivelaz, Anne-Marinette Thi Phuong Hanh Cao

Pioneer transcription factors (pTFs) bind to target sites within compact chromatin, initiating chromatin remodeling and controlling the recruitment of downstream factors. The mechanisms by which pTFs overcome the chromatin barrier are not well understood. ...

A genetic algorithm based design and experimental characterization of a highly thermostable metalloprotein

Ursula Röthlisberger, Rudolf Hovius, Esra Bozkurt, Marta Andreia Da Silva Perez, Nicholas John Browning

The development of thermostable and solvent-tolerant metalloproteins is a long-sought goal for many applica- tions in synthetic biology and biotechnology. In this work, we were able to engineer a highly thermo- and organic solvent- stable metallo variant o ...

Evaluating Cellular Drug Uptake with Fluorescent Sensor Proteins

Kai Johnsson, Rudolf Hovius, Rudolf Griss, Kui Thong Tan, Silvia Scarabelli

We are introducing a new approach to evaluate cellular uptake of drugs and drug candidates into living cells. The approach is based on converting the protein target of a given class of compounds into a fluorescent biosensor. By measuring the binding of dif ...

Tetrahydrobiopterin Biosynthesis as a Potential Target of the Kynurenine Pathway Metabolite Xanthurenic Acid

Kai Johnsson, Rudolf Hovius, Hirohito Haruki, Miriam Grønlund Pedersen

Tryptophan metabolites in the kynurenine pathway are up-regulated by pro-inflammatory cytokines or glucocorticoids, and are linked to anti-inflammatory and immunosuppressive activities. In addition, they are up-regulated in pathologies such as cancer, auto ...
