Amyloid-Forming peptide GNNQQNY is a biological active peptide. (This is a heptapeptide from the N-terminal prion-determining domain of the yeast protein Sup35 that forms amyloid fibrils. The availability of its detailed atomic oligomeric structure makes it a good model for studying the early stage of aggregation. The GNNQQNY dimer forms three stable sheet structures. in-register parallel, off-register parallel, and anti-parallel. The in-register parallel dimer, which is close to the amyloid beta-sheet structure, has few interpeptide hydrogen bonds, making hydrophobic interactions more important and increasing the conformational entropy compared to the anti-parallel sheet.)

β4-TAT is a kind of β-sheet peptide foldamer. β4-TAT is composed of two parts: the β4 sequence (derived from the β-sheet fragment of the RRM domain of fused in sarcoma (FUS)) and the TAT sequence (a nuclear localization signal peptide that helps the entire peptide penetrate the nuclear membrane). β4-TAT influences FUS aggregation by targeting its RNA recognition motifs (RRM). β4-TAT effectively induces FUS aggregation within cells, leading to the death of cancer cells. β4-TAT can be used for the study of FUS .
