Figure 6. Schematic Drawing of a PDZ and an IRS-1 PTB DomainA shared peptide-binding motif is highlighted in red. In both domains bound peptide, shown in yellow, forms an antiparallel β sheet with the β strand flanking the peptide-binding groove. The schematic of the IRS-1 PTB domain is based on [39].
