text: Although ELPs generally form reversible spherical aggregates due to their proline and glycine content, there is a possibility that, under certain conditions such as exceedingly high temperatures, ELPs will form amyloids, or irreversible aggregates of insoluble protein.  It is also believed that changes in the ELP backbone leading to a reduction in the proline and glycine content may lead to ELPs with a greater propensity for the amyloid state. As amyloids are implicated in the progression of Alzheimer's disease as well as in prion-based diseases, such as Creutzfeldt-Jakob disease (CJD), modeling of ELP amyloid formation may be useful from a biomedical standpoint.
