Effect of Grafting on Aggregation of Intrinsically Disordered Proteins.


ABSTRACT: A significant part of the proteome is composed of intrinsically disordered proteins (IDPs). These proteins do not fold into a well-defined structure and behave like ordinary polymers. In this work, we consider IDPs that have the tendency to aggregate, model them as heteropolymers that contain a small number of associating monomers, and use computer simulations to compare the aggregation of such IDPs that are grafted to a surface or free in solution. We then discuss how such grafting may affect the analysis of in vitro experiments and could also be used to suppress harmful aggregation.
