Protein Translocation through a Nanopore (IMAGE) University of Pennsylvania Caption The zipped (left) and unzipped (right) forms of the protein GCN4-p1passing through a pore are shown. The differences in shape between the dimer and monomer versions of the protein translate to changes in charge, which can be read by electronics surrounding the nanopore.
