RT Journal Article T1 Synthetic peptide scaffolds as ion channels and molecular carriers A1 Pérez-Pérez, Manuel A1 Fuertes, Alberto A1 Montenegro García, Javier K1 Canales iónicos K1 Péptidos K1 Andamiajes moleculares AB Transmembrane ion exchange controls biological functions and is essential for life. Over the years, a great variety of nature-inspired artificial ion channels and carriers have been synthesized to control and promote ion exchange across biological membranes. In this context, peptides emerged as ideal scaffolds for synthetic ion channels due to their biocompatibility, accessibility and chemical versatility. Peptides have already shown their potential for the construction of a range of synthetic ion transporters either alone or in combination with other molecular scaffolds. Among the great diversity of peptide-based ion transporters, we can find key examples of single-molecule and supramolecular transmembrane ion channels and ionophores. Peptide scaffolds have also found great potential for the transmembrane delivery of biomolecular cargos such as nucleic acids and proteins. This review covers some of the most relevant advances in the peptide-based ion transport field from the last few years.
