Structure and function of a Notch-like proteolytic switch domain in the extracellular matrix receptor dystroglycan

Authors : Anderson, Michael J.M. (2023)

The adhesion receptor dystroglycan provides a critical mechanical link between the extracellular matrix (ECM) and the actin cytoskeleton to help muscle cells withstand contraction and neural cells maintain the blood brain barrier. Disrupting the link is associated cancer and muscular dystrophy. Proteolysis of dystroglycan by matrix metalloproteinases (MMPs) provides a mechanism to break the mechanical anchor and is amplified in several pathogenic states,&...

VHL ligand binding increases intracellular level of VHL

Authors : Frost, Julianty (2021)

The von–Hippel Lindau (VHL) protein is a tumour suppressor protein frequently mutated in the VHL disease, which functions as substrate recognition subunit of a Cul2 E3 ubiquitin ligase (CRL2VHL). CRL2VHL plays an important role in oxygen sensing, by binding and targeting Hypoxia Inducible Factor-alpha subunits (HIF-alpha) for ubiquitination and degradation. VHL is also commonly hijacked by heterobifunctional degrader molecules known as...
