Randomized trial shows hydrogel formation is essential for yeast viability, indicating nuclear pore function importance.

This study aims to understand the role of FG-rich nucleoporins in forming a selective permeability barrier in nuclear pore complexes.
Investigated the cross-linking interactions of FG-repeat domains in nuclear pore proteins.
Demonstrated the formation of elastic, reversible hydrogels through phenylalanine-mediated interactions.
Evaluated the necessity of hydrogel formation for yeast viability.
Confirmed that FG-repeat domains cross-link into hydrogels, facilitating selective nucleocytoplasmic transport.
Found that disruptions in this hydrogel structure impair nuclear transport and affect yeast survival.

Frey et al. (2006) studied this question.
