While the topological analysis of protein complexes by electron microscopy (EM) has developed in recent years, the exact position of single subunits within multisubunit complexes has been difficult. A new clonable peptide tag, which when attached to a target protein can recruit a structurally prominent label that is easily identifiable by EM, may help solve this problem.
