Nanobody Loop Mimetics enhance Sos1-Catalyzed Nucleotide Exchange on RAS
We show that peptides mimicking the CDR3 of a Nanobody can modulate protein-protein interactions
Jacob and Louise Gabbay Award
Jan Steyaert is the 24th (2022) winner of the Jacob and Louise Gabbay Award in Biotechnology and Medicine in recognition of his contributions to structural biology through the development of Camelid single-domain antibodies or nanobodies
Structural basis of sodium-dependent bile salt uptake into the liver
Nanobodies developed in our lab were instrumental to solve different structures of the human NTCP, revealing key conformations of its transport cycle. NTCP is the main bile salt uptake system in liver and is the cellular entry receptor of human hepatitis B and D viruses.
Structure and mechanism of hyaluronan synthase
Different cryo-EM structures of the hyaluronan synthase provide insights into the biosynthesis of one of the most abundant and essential glycosaminoglycans in the human body
2nd Nanobody meeting in Brussels
As Nanobodies were born at the University of Brussels, the VIB-VUB Center for Structural Biology was very honored to organize the hybrid second edition of bianual Nanobody conferences.
Megabodies for cryo-EM
New nanobody-based tools to improve structure determination by single-particle cryo-EM
A scientific 'power couple' with one of the largest publishing networks in biology
According to Dimensions data, they have co-authored 101 papers together since 2009, 45 of which were published in journals tracked by the Nature Index. They also hold 93 patents related to their nanobodies technique.
GABAA receptor structures
We reported several high-resolution cryo-electron microscopy structures of the human heterotrimeric GABAA receptor bound to several ligands including alprazolam and diazepam.
Developing Nanobody-enabled conformational fragment screening
By fusing Nanobodies that exhibit G protein-like behavior, we were able to lock GPCRs constitutively in their active conformation. These GPCR-Nb fusions have a unique pharmacological profile.
Spinning out Confo Therapeutics
Confo Therapeutics’ unparalleled technology stabilizes functional conformations of GPCRs (G protein-coupled receptors) to uncover a wide range of previously inaccessible GPCRs as drug targets.
Unveiling conformational states of membrane pumps
Nanobodies from our lab were instrumental to lock and solve the structures of inward-facing conformations of P-glycoprotein, LacY, an Fe2+ transporter, a fumarate transporter and the mitochondrial ADP-ATP transporter.
Nanobodies to investigate GPCR dynamics inside cells
In collaboration with several groups, we started applying our Nbs as versatile tools for the investigation of GPCR dynamics at the molecular and the sub-cellular level in vitro or as intrabodies inside cells.
Crystal Structure of the first GPCR-Gs protein complex
In collaboration with the Kobilka lab we generated Nb35 that freezes a transient Adrenergic Receptor-Gs protein complex
Locking agonist-bound active state GPCR conformational states
In collaboration with Brian Kobilka, In collaboration with Brian Kobilka, we generated Nanobodies against the β2 adrenergic receptor (β2AR), the muscarinic acetylcholine receptor (M2R) and the μ-opioid receptor (MOR) that exhibit G protein-like behaviour, and obtained agonist-bound, active-state crystal structures of receptor●Nb complexes of β2AR, M2R & MOR.
