Frédérique Perler

Frédérique Perler. A pioneering Swiss molecular biologist renowned for her groundbreaking discoveries in the field of protein splicing. Her research fundamentally advanced the understanding of introns in proteins, known as inteins, and their mechanisms of self-excision. Perler's work has had profound implications for protein engineering, synthetic biology, and the study of evolutionary biology.

Early life and education

Born in Switzerland, Frédérique Perler developed an early interest in the natural sciences. She pursued her undergraduate studies at the University of Geneva, a leading institution in the life sciences. For her doctoral research, she joined a laboratory focused on nucleic acid biochemistry, earning her PhD from the same university. Her thesis work provided a crucial foundation in enzymology and gene expression, skills she would later apply to novel genetic elements.

Career

Following her doctorate, Perler undertook a postdoctoral fellowship in the United States, working alongside prominent researchers at the National Institutes of Health. She returned to Switzerland to establish her independent research group, first at the University of Basel and later at the prestigious ETH Zurich. Throughout her career, she collaborated extensively with scientists at institutions like the MRC Laboratory of Molecular Biology and the Max Planck Society. She also served on editorial boards for major journals including Nature Structural & Molecular Biology and The EMBO Journal.

Research and contributions

Perler's most significant contribution was the discovery and characterization of protein splicing, a process where an internal segment of a polypeptide chain (an intein) excises itself and ligates the flanking sequences (exteins). This work elucidated the mechanism of intein function, revealing parallels to the spliceosome machinery that processes RNA. Her team demonstrated that inteins are mobile genetic elements and detailed the key catalytic residues involved in the self-cleavage reactions. This research provided powerful new tools for biotechnology, enabling novel methods in protein purification and the creation of conditional protein knockout systems. Her findings also offered insights into horizontal gene transfer and the origin of life.

Awards and honors

In recognition of her transformative research, Frédérique Perler received numerous prestigious awards. She was a recipient of the Swiss Science Prize Marcel Benoist, often considered Switzerland's highest scientific honor. She was elected as a member of both EMBO and the European Molecular Biology Organization. Her work was further acknowledged with the Körber European Science Prize and the Novartis Prize in biochemistry. She has delivered invited lectures at major conferences including the Gordon Research Conferences and the International Congress of Biochemistry and Molecular Biology.

Personal life

Frédérique Perler is known to have maintained a private life while being an active mentor to many young scientists in Basel and Zurich. She has been involved in initiatives to promote women in science, participating in programs organized by the Swiss Academy of Sciences. Outside the laboratory, she has interests in classical music and alpine hiking.
