    SUBCELLULAR LOCALIZATION     intracellular
  • nuclear membrane
  • with SYN1 co-localize in neurons
  • basic FUNCTION
  • a negative regulator of the Wnt/beta-catenin signaling pathway
  • involved in tissue polarity and planar polarity
  • a putative tumor suppressor in hepatocellular carcinoma
  • implicated in the canonical WNT/beta-catenin pathway
  • implicated in the nuclear trafficking of the transcription repressors REST/NRSF and REST4
  • PRICKLE1, PRICKLE2 possibly regulate positive neurite formation during brain development
  • PRICKLE1 and PRICKLE2 promote neurite-like process formation of neuroblastoma cells via the DVL1 dependent mechanism
  • function in the noncanonical WNT signaling pathway, which regulates intracellular calcium release and planar cell polarity (PCP)
  • having function in axonal-dendritic development associated with the maturation of CNS neurons
  • part of the noncanonical or planar cell polarity (WNT/PCP) pathway
  • potentially part of the WNT5A/PCP signaling, regulating cell polarity and affecting expression of multiple factors to stunt limb growth through altered patterns of gene expression, including the PCP genes WNT5a and VANGL2
