Abstract: AbstractBiomolecular condensation of the neuronal microtubule-associated protein Tau (MAPT) can be induced by coacervation with polyanions like RNA, or by molecular crowding. Tau condensates have been linked to both functional microtubule binding and pathological aggregation in neurodegenerative diseases. We find that molecular crowding and coacervation with RNA, likely coexisting in the cytosol, synergize to enable Tau condensation at physiological buffer conditions and produce condensates with a strong affinity to charged surfaces. During con...
