Throughout his research career, Dr Saponaro has focused on studying and characterising genome stability maintenance, using several biological systems and techniques. During his PhD in the Foiani lab he characterised the relevance of the CDK1-dependent phosphorylation of the DNA helicase Srs2, discovering that Srs2 is one of the first identified targets of CDK1 in the double strand break repair in S. cerevisiae. He has also been involved in the characterisation of the role of Sen1 (homolog of SETX, mutated in the neurodegenerative disorders AOA2 and ALS4) in genome stability maintenance and in its role in coordinating transcription and replication.
After being appointed as a Birmingham Fellow he has expanded and developed his research interests. In particular, he is characterising how and why RNA Pol II transcription can become source of genomic stress, implementing and expanding the genome wide approaches he currently uses. The interface between transcription and genomic instability in higher eukaryotes is an emerging field, with many open questions. The research program will aim not only to describe a phenotype, but also to understand the mechanism behind it. These studies will help clarifying how the two biological fundamental processes of transcription and replication can coexist, how they are coordinated and how they impact on each other. This is not only a fundamental biological problem but has clear implications for human health.
