... with respect to the fibril growth rates. In the case of N-WT, the conversion to the fibrillar confor- mation is presumably very slow under the applied conditions. This assumption, and the fact that ... seeds lose their activity upon incubation, may be responsible for the only moderate acceleration of fibril formation of N-WT by seeds. Consequently, an increase in the protein concentration and ⁄ ... concentra- tions of PABPN1 close to poly(A) tails. Because fibril formation, like other aggregation processes, is known to be a concentration-dependent reaction, the absence of nuclear inclusions...

These findings pave the way to future studies of the mechanism of formation of FXR-containing ribonu- cleoprotein granules and suggest a possible link with the ... sedimen- tation (data not shown). To verify the morphology of the end-states of aggre- gation, we used transmission electron microscopy and examined samples after the conformational transition Fig....
