Description générale

Research area: Cancer

The von-Hippel Lindau tumor suppressor (VHL) complex is a multi-subunit ubiquitin ligase composed of VHL, Elongin B, Elongin C, Cul2 and Rbx1. The VHL protein serves as the substrate recognition component and is linked by Elongin C to a heterodimeric Cul2/Rbx1 module that functions as a potent activator of the ubiquitination of target proteins by an E2 conjugating enzyme. Elongin B interacts with the complex through Elongin C and appears to stabilize the binding of Elongin C to VHL.

Application

Ubiquitination Cascade Comoponent: E3

Actions biochimiques/physiologiques

The primary function of the von-Hippel Lindau tumor suppressor (VHL) complex is to regulate HIF (hypoxia inducible factor) activity by targeting the hydroxylated HIF-1α subunit for ubiquitination and rapid proteasomal degradation during normoxia under normoxic conditions. It therefore plays an important role in the regulation of hypoxia-inducible genes such as the vascular endothelial growth factor (VEGF) and glucose transport-1 (Glut-1). Mutations in VHL are associated with the inherited von Hippel-Lindau (VHL) cancer syndrome and numerous forms of renal cell carcinoma.

Forme physique

Purified using glutathione sepharose.

Hypoxia-Inducible Factors (HIFs) are heterodimeric oxygen-sensitive basic helix-loop-helix transcription factors that play central roles in cellular adaptation to low oxygen environments. The von-Hippel Lindau tumor suppressor (pVHL) is the substrate recognition component of an E3 ubiquitin ligase and functions as

Activation of dual-specificity tyrosine-phosphorylation-regulated kinases 1A and 1B (DYRK1A and DYRK1B) requires prolyl hydroxylation by PHD1 prolyl hydroxylase. Prolyl hydroxylation of DYRK1 initiates a cascade of events leading to the release of molecular constraints on von Hippel-Lindau (VHL) ubiquitin ligase
