Exploratory experiment designed to discover new patterns targeting N/A in mammalian cells. Primary outcome: Phase separation properties of DDR protein condensates
This experiment investigated the mechanism by which damage-induced long non-coding RNAs (dilncRNAs) promote the concentration of DDR proteins into foci. The researchers demonstrated that dilncRNAs drive molecular crowding of DDR proteins such as 53BP1 into condensates that exhibit properties of liquid-liquid phase separation. This study provided mechanistic insight into how RNA synthesis at DSB sites contributes to the physical organization of DDR factors into discrete, membrane-less compartments with specific biophysical properties.
