- Abstract
The aggregation of amyloidogenic proteins is often related to the occurrence of neurodegenerative diseases, including fused in sarcoma protein (FUS) in frontotemporal lobar degeneration and amyotrophic lateral sclerosis diseases. Recently, the SERF protein family has been reported to have a significant regulatory effect on amyloid formation, but it is still unclear about the detailed mechanisms of SERF acting on different amyloidogenic proteins. Herein, nuclear magnetic resonance (NMR) spectroscopy and fluorescence spectroscopy were used to explore interactions of ScSERF with three amyloidogenic proteins FUS‐LC, FUS‐Core, and α‐Synuclein. NMR chemical shift perturbations reveal them sharing similar interaction sites on the N‐terminal region of ScSERF. However, the amyloid formation of α‐Synuclein protein is accelerated by ScSERF, while ScSERF inhibits fibrosis of FUS‐Core and FUS‐LC proteins. Both the primary nucleation and the total amount of fibrils produced are detained. Our results suggest a diverse role of ScSERF in regulating the fibril growth of amyloidogenic proteins.
