An aminoglycoside antibiotic drives RNA phase separation
Aminoglycoside antibiotics bind RNA with high affinity through networks of amine and hydroxyl contacts, yet whether this multivalent binding can drive macroscopic RNA phase transitions has never been tested. Here we show that neomycin B (neoB), an FDA-approved aminoglycoside, induces concentration-dependent phase separation of poly(A), poly(U), and total E.coli RNA. Condensate size and density…
