摘要

In this paper, the Sequential Collapse Model (SCM) for protein folding pathways is applied to investigate the location of the non-local contacts in the intrinsically disordered state of a-synuclein, a protein implicated in the onset and spreading of several serious neurodegenerative diseases. The model relies on the entropic cost of forming protein loops due to self-crowding effects, and the protein sequence to determine contact location and stability. It is found that the model predicts the existence of several possible non-local contacts, and the location of the non-local contacts is consistent with existing experimental evidence. The bearing of these findings on the pathogenic mechanism and its regulation is discussed.
