Synthetic biologists along with structural biologists have explored ways to fold artificial proteins into diverse shapes like origamis. They constructed diamond-shaped protein cages, and managed to transform them to different shapes. Similar technology exists for DNA, but origami proteins could have more applications, e.g. in making new materials, delivering drugs and vaccines, and more. https://www.sciencedaily.com/releases/2021/04/210412114829.htm
