Crosstalk Between Phase-Separated Membraneless Condensates and Membrane-Bound Organelles in Cellular Function and Disease.

Compartmentalization in eukaryotic cells allows the spatiotemporal regulation of biochemical processes, in addition to allowing specific sets of proteins to interact in a regulated as well as stochastic manner. Although membrane-bound organelles are thought to be the key players of cellular compartmentalization, membraneless biomolecular condensates such as stress granules, P bodies, and many others have recently emerged as key players that are also thought to bring order to a highly chaotic environment. Here, we have evaluated the latest studies on biomolecular condensates, specifically focusing on how they interact with membrane-bound organelles and modulate each other's functions. We also highlight the importance of this interaction in neurodegenerative and cardiovascular diseases as well as in cancer.
