Self-Associating Peptides for Modular Bifunctional Conjugation of Tetramer Macromolecules in Living Cells

Monitoring the assembly of macromolecules to design entities with novel properties can be achieved either chemically creating covalent bonds or by noncovalent connections using appropriate structural motifs. In this report, two self-associating peptides (named K3 and E3) that originate from p53 tetramerization domain were developed as tools for highly specific and noncovalent heterotetramerization of two biomolecules. The pairing/coupling...
