Nature study finds liquid-like motion in the nuclear pore transport barrier
Nature reported that NUP98 proteins in the nuclear-pore barrier move dynamically in living cells, with importin-beta and a sugar modification helping maintain that state.
A Nature research briefing describes experiments and simulations indicating that flexible proteins in the nuclear-pore transport barrier behave in a liquid-like way. The report says importin-beta and glycosylation help preserve the barrier's dynamic state.
