About the Steyaert lab

The Brussels based VIB-VUB Center for Structural Biology (CSB) is part of the VIB life sciences institute (VIB) and is embedded within the Vrije Universiteit Brussel (VUB). We study the structure and dynamics of macromolecular complexes in health and disease to explain their mode of action. We integrate our structural biology work with genetic and cellular studies, aiming to bridge molecular and cellular resolution. We excel in translating our discoveries into biotechnological and medical applications.

The Steyaert labpioneered the use of Nanobodies in structural biology. By rigidifying flexible regions and obscuring aggregative surfaces, nanobody complexes warrant conformationally uniform samples that are key to protein structure determination by X-ray crystallography. The elucidation of the first GPCR structure in its active state using a conformationally selective Nanobody demonstrates the power of the Nanobody platform to generate diffracting quality crystals of the most challenging targets including membrane proteins, flexible proteins, aggregating proteins and protein-protein complexes.

Your Job

The Steyaertlab demonstrated that Nanobodies can be selected stabilize the ß2AR-Gs complex. One of these nanobodies that inhibits the GTP driven dissociation of ß2AR-Gs was instrumental for obtaining the high-resolution crystal structure of this complex, providing the first view of  transmembrane signaling by a GPCR (link to Nature paper). Building on these data, we aim at stabilizing other GPCR-transmembrane signaling complexes, making them amenable to innovative drug discovery approaches. This project runs in collaboration with spin-off company Confo Therapeutics.
