The hook
Apple's SimpleDesign tackles protein sequence-structure codesign — a key frontier in AI-assisted drug discovery.
Proteins are fundamental to biological processes, with their function determined by the complex interplay between the amino acid sequence and the three-dimensional structure. Developing generative models capable of understanding this intrinsically multi-modal relationship is crucial for fields like …
