Sommario/riassunto |

Sheds new light on intrinsically disordered proteins and peptides, including their role in neurodegenerative diseases With the discovery of intrinsically disordered proteins and peptides (IDPs), researchers realized that proteins do not necessarily adopt a well defined secondary and tertiary structure in order to perform biological functions. In fact, IDPs play biologically relevant roles, acting as inhibitors, scavengers, and even facilitating DNA/RNA-protein interactions. Due to their propensity for self-aggregation and fibril formation, some IDPs are involved in neurodegenerative dis |
