Figure 1: Kapβ2 bound to bPY-NLS of hnRNP M. Despite a common Kapβ2 interface, functional groups in the hnRNP M basic 50-KEKNIKR-56 motif are very different from those in the hnRNP A1 hydrophobic ...
All proteins are made of basic secondary structure units, either α-helix or β-sheets, determined by hydrogen bonding between the amino acids within a peptide chain. On a larger scale, structures are ...
