Abstract

Small molecule-regulated protein oligomerization provides a powerful mechanism for manipulating biological processes by controlling protein proximity with high temporal precision. However, such systems only rarely exist in nature and remain a substantial challenge for de novo design. In this work, we describe a computational method for designing protein homooligomers whose assembly is regulated by small-molecule ligands with matching symmetry. We designed protein homotrimers regulated by the Food and Drug Administration (FDA)-approved drug amantadine and further designed amantadine-responsive heterodimers and heterotrimers. Biophysical characterization confirmed their amantadine-dependent assembly, and their…
