Biomolecular condensates are micron-scale compartments in eukaryotic cells that operate to concentrate proteins and nucleic acids but lack surrounding membranes. RNA metabolism, ribosome biogenesis, the DNA damage response, and signal transmission are all affected by these condensates. Recent research has discovered that multivalent macromolecular interactions promote liquid-liquid phase separation, which is a fundamental organizing principle for biomolecular condensates. At spindle matrix, BuGZ undergoes phase separation to promote assembly of spindles and their associated components (26388440).
