Building Proteins in a Day: Efficient 3D Molecular Reconstruction

Brubaker, Marcus A., Punjani, Ali, Fleet, David J.

Understand

Discovering the 3D atomic structure of molecules such as proteins and viruses is a fundamental research problem in biology and medicine.

  • Electron Cryomicroscopy (Cryo-EM) is a promising vision-based technique for structure estimation which attempts to reconstruct 3D structures from 2D images.
  • This paper addresses the challenging problem of 3D reconstruction from 2D Cryo-EM images.
  • A new framework for estimation is introduced which relies on modern stochastic optimization techniques to scale to large datasets.
