Serine(S)/threonine(T)-glutamine(Q) cluster domains (SCDs). polyglutamine (polyQ) tracts and polyglutamine/asparagine (polyQ/N) tracts are Q-rich motifs found in many proteins. SCDs often are intrinsically disordered regions that mediate protein phosphorylation and protein-protein interactions. PolyQ and polyQ/N tracts are structurally flexible sequences that trigger protein aggregation. https://www.nacrack.com/quick-sale-Graffiti-Chicago-Refection-Skyline-Canvas-super-sale/
