    basic FUNCTION
  • can specifically deubiquitinate and stabilize HIF1A and, therefore, increase expression of HIF-1alpha targeted genes, such as vascular endothelial growth factor (VEGF)
  • USP33 and USP20 coordinate ADRB2 recycling and resensitization
  • function of USP20 in genome maintenance and DNA repair
  • is critical for replication stress response
  • roles of USP18 and USP20 in mediating virus-triggered signaling
  • USP20 regulates actin cytoskeleton organization and cell migration in a manner dependent on MAPK6 expression
  • USP20 plays a crucial role in autophagy initiation by maintaining the basal expression level of ULK1

    INTERACTION

    small molecule
    protein
  • interacts with HIF-1alpha
  • USP20 is a key negative regulator of TAX-induced NFKB1 signaling
  • regulates the reciprocal functions of ARRB2 in TLR4-promoted Nuclear Factor kappaB (NFKB) activation
  • function of HERC2/USP20 in coordinating CHEK1 activation by modulating CLSPN stability, which ultimately promotes genome stability and suppresses tumor growth
  • ubiquitination by the E3 ligase NEDD4 and deubiquitination by the deubiquitinases USP20 and USP33 have been shown to regulate the lysosomal trafficking and recycling of agonist-activated ADRB2
  • USP20 is a novel MAPK6 regulator (USP20 interacts with and deubiquitinates MAPK6 both in vitro and in intact cells)
  • USP20 is a positive regulator of CLSPN and suppresses the malignant characteristics of gastric cancer cells
  • USP20 acts as a positive regulator of autophagy initiation through stabilizing ULK1
    • cell & other
    REGULATION
    Phosphorylated by ATR, resulting in disassociation of the E3 ubiquitin ligase HERC2 from USP20 and USP20 stabilization
