    basic FUNCTION
  • organelle transport and neurite outgrowth
  • putatively anchoring MYO5A in particular cell domains via its interaction with alpha actinin 4, ACTN4
  • E3 ligase that mediates activity-dependent turnover of PSD scaffold proteins and is a negative regulator of dendritic spine morphology (Hung 2010)
  • may act at a posttranscriptional level to regulate the intracellular trafficking of GABAA receptor (Cheung 2010)
  • unique TP53-regulated gene that modulates seizure susceptibility and GABAAR cell surface expression (Cheung 2010)
