- Non-canonical roles of mitotic proteins in cortical neuronsPublication . Cavaco, Joana Sofia de Almeida Pimentel; Carvalhal, SaraMitotic proteins are traditionally studied for their role in chromosome segregation during cell division. However, research increasingly highlights the important noncanonical roles of mitotic proteins beyond mitosis, particularly in the mammalian cerebral cortex. Alterations in the expression levels or mutations of mitotic proteins are increasingly linked to brain disorders such as primary microcephaly and Alzheimer’s disease. A central, unresolved question remains: how do mitotic proteins contribute to neuronal pathogenesis? Here, we review emerging literature on the non-canonical roles of mitotic proteins in mature neurons. Additionally, we discuss how these contribute to the complex mechanisms underlying neurodevelopmental and neurodegenerative disorders. We also discuss their potential for identifying therapeutic strategies and as biomarkers in brain pathologies.
