Title: Watching a Chaperone Fold a Protein at High Resolution

Refreshments at 11:15 am.

Date: Fri, 29 Sep 2017, 11:30 am – 12:30 pm

Type: Seminar

Location: 1400 BPS Bldg.

The Bardwell laboratory has addressed four of the central mysteries of chaperone biology: how chaperones rapidly bind to proteins, how the chaperone-substrate complex is stabilized, how a chaperone can facilitate substrate folding, and what triggers substrate release1,2. The laboratory has also devised a novel structural biology approach that enabled us to visualize the dance of chaperone-mediated folding1,4 demonstrating that client folding occurs while bound to the chaperone3.
