Ubiquitin (-like) signaling and Proteomics
After obtaining an EMERGIA 2020 grant from the Andalusian Regional Government and being selected in the Ramon y Cajal 2020 program from the Spanish Ministry of Science I have recently joined CABIMER as an Emerging PI and visiting Scientist.
Since May 2018, I am a Senior Researcher and independent Junior PI in the Cell and Chemical Biology Department at the Leiden University Medical Center (LUMC), The Netherlands, after obtaining a Young Investigator Grant from the Dutch Cancer ociety (€k548). This grant enabled me to lead the “Genome (Ubiquitin-like) proteomics” group and hire my first PhD Student.
In my group, we are specialized in the identification and characterization of ubiquitination substrates in a ubiquitin ligase-specific manner employing our own developed TULIP2 methodology (Salas-lloret et al. 2019).
Previously, from February 2013 to May 2018 I was a postdoc in Alfred Vertegaal’s group at the LUMC, studying the role of the Small Ubiquitin-Like Modifier (SUMO) in DNA repair and Cancer progression. I published four first author publication and was allowed to lead my DNA repair-related projects, which is reflected in two corresponding author publications (Gonzalez-Prieto et al. 2015a, Gonzalez-Prieto et al. 2015b, Kumar,Gonzalez-Prieto et al. 2017, Gonzalez-Prieto et al 2021). Furthermore, I participated in several collaborative projects.
I did my PhD in Felix Prado’s group at CABIMER/CSIC, Seville, Spain. studying the role of the Homologous Recombination machinery during DNA replication and its control by cell cycle, which was published in EMBO Journal (Gonzalez-Prieto et al. 2013).
Previous to my PhD, I worked in the Gañan-Calvo group at the School of Engineering, University of Seville, Spain. My project aimed to develop biomedical application to their developed technology, Flow Focusing, I discovered a new microfluidic phenomenon, which was published in Nature Physics (Gañan-Calvo et al. 2007).
We study the role of ubiquitin(-like) signaling in the regulation of Genome biology- and cancer-relevant E3 enzymes specific targets.
We use mass spectrometry-based proteomics tools to identify the specific substrates of E3 enzymes which have a role in genome biology. Misregulation of these E3 enzymes leads to the appearance of cancer. Furthermore, we employ cell biology, biochemistry, and molecular biology techniques to unravel the function that ubiquitin signaling has in the regulation of the activity of these ubiquitin target proteins.
Among others We apply it on ubiquitin ligases relevant in DNA repair and cancer. Particularly, this grant aims to identify the specific substrates for the BRCA1/BARD1 heterodimer, which deficiency is the first cause of hereditary breast and ovarian cancer. The role of the ubiquitin ligase activity of BRCA1/BARD1 in DNA repair and Cancer remains controversial.
Post translational modifications play a very important role in the fine tuning of protein function. These modifications can consist in the addition of small chemical groups or the covalent attachment of other small proteins. Among the small proteins that can be attached to other proteins, the most relevant one is ubiquitin.
Ubiquitination consists of a cascade reaction performed by the so called E1, E2 and E3 enzymes. More than 600 E3 enzymes are encoded in the human genome. In the lab, we combine mass-spectrometry based proteomics approaches to identify E3-specific ubiquitination substrates with molecular biology, biochemistry and cell biology techniques to unravel the role of ubiquitination on the regulation of these ubiquitinated proteins.
Ubiquitin signaling is involved in practically every single cellular process, having a very high importance in the organisational dynamics of the genome including the DNA damage response. The DNA damage response consists of the plethora of signaling pathways and enzymatic activities that cells are endorsed with in order to overcome the different sources of DNA damage that challenge the integrity of their genomes.

The DNA damage response consists of the plethora of signaling pathways and enzymatic activities that cells are endorsed with in order to overcome the different sources of DNA damage that challenge the integrity of their genomes.
Deficiencies in the DNA damage response cause genome instability, which is one of the hallmarks of cancer.
The aim of our research is to discover new components of the DNA damage response machinery that could become targets of anti-cancer treatments in the future.
