The Dikic laboratory focuses on studying molecular mechanisms of the two major degradation pathways – the ubiquitin-proteasome system (UPS) and autophagy. Degradation of cellular components, either through the UPS or the lysosome (autophagy), is essential for maintaining cellular homeostasis. Disruption to either of the processes can lead to neurodegenerative diseases, cancer and other pathologies. It is critical to understand the structure and function of individual components within each of these pathways.
The IBCII is equipped with the state-of-the-art technology, allowing us an easy access to the tools and equipment needed to address outstanding questions in the field. This, coupled with the close collaboration with other groups, gives us the opportunity to carry out high-quality science, with the aim for our research to eventually be translated into medicine.
Innate immunity and viral spread are regulated by the SARS-CoV-2 papain-like protease
In early 2020, the outbreak of SARS-CoV-2 caused laboratories to close and scientists to work from home. With a view to tackling the virus, we joined forces with labs across Europe to contribute to the growing research on SARS-CoV-2. We focused on SARS-CoV-2 papain-like protease, PLpro, and compared it to previously characterised PLpro from SARS. PLpro can cleave small proteins such as ubiquitin or ISG15 from target proteins. We found that SARS-CoV-2 PLpro specifically cleaves ISG15 from its substrates, compared to SARS PLpro that specifically cleaves ubiquitin.... (read more)

Adriana was born in La Serena, Chile. She obtained her Agronomic sciences degree at the University of La Serena. Her thesis was focused on the tolerance strategies under abiotic stress in Chenopodium quinoa. Adriana then decided to study a PhD in Cellular and Molecular Biology at the University Austral of Chile, Valdivia (Chile). Her research was dedicated in the Vitamin C homeostasis at the Central Nervous System and first focused on how ascorbic acid regulates the trafficking of SVCT2 transporter and second how the failure in the ascorbic acid homeostasis impaired the glucose uptake modulation in Huntington disease under the supervision of Dr. Maite A. Castro. In November 2017 Adriana joined the laboratory of Molecular Signaling of Prof. Dikic as a Postdoctoral researcher investigating the role of linear ubiquitination in the remodeling heart during myocardial infarct. Also, Adriana is currently studying novel mechanisms involved specifically in the regulation of ER-phagy.
