WebOct 22, 2014 · The von Hippel-Lindau tumor suppressor protein (VHL) recruits a Cullin 2 (Cul2) E3 ubiquitin ligase to downregulate HIF-1α, an essential transcription factor for the hypoxia response. Mutations in VHL lead to VHL disease and renal cell carcinomas. Cullin 3 is a component of Cullin-RING E3 ubiquitin ligases complexes (CRLs) which are involved in protein ubiquitylation and represent a part of ubiquitin–proteasome system (UPS). Added ubiquitin moieties to the lysine residue by CRLs then target the protein for the proteasomal degradation. Cullin-RING E3 ubiquitin ligases are involved in many cellular processes responsible for cell cycle regulation, stress response, protein trafficking, signal transduction, DNA replication, transcriptio…
