UCSF / HHMI

Info

Professor of Biochemistry and Biophysics at UCSF (faculty since 2006) and Howard Hughes Medical Institute Investigator (since 2015). Made foundational contributions to single-particle cryo-EM methodology and its application to membrane protein structure determination. His laboratory, together with David Julius’s group at UCSF, determined the first near-atomic resolution cryo-EM structures of a TRP channel (TRPV1) in 2013. This work was a landmark in the “resolution revolution” that demonstrated cryo-EM could rival X-ray crystallography for small proteins.

DiffUSE relevance

Cheng is at UCSF, the same institution as Jaime Fraser (DiffUSE PI). His cryo-EM expertise represents a complementary structural technique for studying protein dynamics: where diffuse scattering captures dynamics from crystal lattice disorder, cryo-EM captures conformational heterogeneity from single particles in vitreous ice. The two approaches could be integrated for a more complete picture of conformational ensembles.
