摘要
Human prion-like proteins often correspond to nucleic acid binding proteins,displaying both globular domains and long intrinsically disordered regions(IDRs)(Harrison and Shorter,2017).Their IDRs are of low complexity and resemble in amino acid composition to the disordered yeast prion domains,being usually enriched in Gln and Asn residues and depleted in hydrophobic and charged residues.Accordingly,these sequence stretches are named prion-like domains(PrLDs).Prion-like proteins can aggregate into amyloid fibrils,which can accommodate incoming protein monomers,propagating thus the polymeric fold,both processes being。
