Leucine zippers are employed to mediate dimerization of scFv in a miniantibody form.
The new work also clarifies the atomic nature of so-called leucine zippers stretches of amino acids that bind two proteins into two-molecule complexes called dimers, which regulate gene activity Confirmation that leucine zippers are actually coiled coils will help scientists understand how these proteins regulate the on-and-off switching of genes, comments Steven L.
In 1988, McKnight named this hydrophobic section the leucine zipper because he and his colleagues thought the leucines from two proteins lined up in such a way that they interlocked like teeth in a zipper.
Sometimes the leucine zipper helps two different molecules link up, says Kim.
