Our group is interested in the physiological and pathological functions of proteins related to damage in the central nervous system (CNS), and how post-translational modifications influence them. We are currently concentrating efforts on the role of astroglia in CNS pathologies and the intracellular pathways that control it, such as the JAK/STAT3 pathway. We are also interested in protein complementation, a fundamental property observed in many proteins, such as ubiquitin, the green fluorescent protein family, thymidine kinase or luciferase. These proteins can be split in two or more fragments that are not functional, but that recover their function when they are brought back together by non-covalent bonds. Protein complementation could be used as a therapeutical tool for human pathologies involving protein truncations or mutations, as well as a biotechnological tool for research purposes.
