PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N-terminal C3HC4 RING finger domain
  • a WWE domain, that recognizes poly(ADP-ribose) (PAR) by interacting with iso-ADP-ribose (iso-ADPR), the smallest internal PAR structural unit containing the characteristic ribose-ribose glycosidic bond formed during poly(ADP-ribosyl)ation
  • a PAR binding motif (PBM)
  • HOMOLOGY
    interspecies homolog to rattus LOC308051
    Homologene
    FAMILY
  • zinc finger family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytosolic
    intracellular,cytoplasm,cytoskeleton,microtubule,centrosome
    text cytoplasmic protein that also prevents tankyrase protein aggregation at a centrosomal location
    basic FUNCTION
  • likely functioning as a ubiquitin protein ligase
  • may function early in the progression of neurodegenerative diseases
  • promotes Wnt signalling by mediating tankyrase-dependent degradation of axin
  • RNF146-dependent protein degradation may emerge as a major mechanism by which tankyrase exerts its function
  • RING-type ubiquitin E3 ligase, and a positive regulator of Wnt signaling that operates with tankyrase to maintain low steady-state levels of Axin proteins
  • PAR-dependent ubiquitin E3 ligase, and its ligase activity requires PAR binding
  • PAR-dependent E3 ligase that regulates cell survival and DNA repair
  • is likely to regulate a variety of cellular processes where PARsylation plays a role
  • controls osteoclast activity by regulating SH3BP2 levels in an ADP-ribose-dependent manner
  • CELLULAR PROCESS protein, degradation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • TNKS-RNF146-AMOT axis is an upstream pathway regulating YAP1
  • a component
  • ubiquitin ligase complex
  • RNF146, tankyrase, and Axin form a protein complex, and RNF146 mediates ubiquitylation of all three proteins to target them for proteasomal degradation
  • INTERACTION
    DNA
    RNA
    small molecule metal binding,
  • ion Zn2+
  • protein
  • directly interacts with poly(ADP-ribose) through its WWE domain, and promotes degradation of PARsylated proteins
  • BLZF1 and CASC3 are further substrates targeted by tankyrase and RNF146 for degradation
  • destabilizes tankyrases TNKS1 and TNKS2 proteins and, in a reciprocal relationship, tankyrase activity reduces RNF146 protein levels
  • binds and ubiquitinates both PARsylated and PAR binding proteins via its PBM, marking these proteins for ubiquitin proteasomal degradation
  • is the functional E3-ligase controlling SH3BP2 protein levels
