ENGINEERING A MISFOLDED FORM OF CD2
OverviewOverview
The amino-terminal domain of CD2 has the remarkable ability to fold in two, ways: either as a monomer or as an intertwined, metastable dimer. Here we, show that it is possible to differentially stabilize either fold by, engineering the CD2 sequence, mimicking random mutagenesis events that, could occur during molecular evolution. Crystal structures of a, hinge-deletion mutant, which is stable as an intertwined dimer, reveal, domain rotations that enable the protein to further assemble to a, tetramer. These results demonstrate that a variety of folds can be adopted, by a single polypeptide sequence, and provide guidance for the design of, proteins capable of further assembly.
