    basic FUNCTION
  • involved in ubiquitin-dependent protein catabolism
  • tumor suppressor role of USP46 in promoting PHLPP1 expression and inhibiting AKT1 signaling in colon cancer
  • role of the DUB (deubiquitinating enzyme) USP46 in the nervous system
  • CELLULAR PROCESS protein, degradation
    protein, ubiquitin dependent proteolysis

    INTERACTION

    small molecule
    protein
  • interacting with WDR20 (WDR20, a WD40-repeat containing protein, is a common binding partner of WDR48, USP12, and USP46) (Kee 2010)
  • binds to PHLPP1 and directly removes the polyubiquitin chains from PHLPP1 in cells
  • WDR48 interacts with the USP46 fingers subdomain via a relatively small, highly polar surface on the top center of the WDR48 beta propeller
  • WDR48 is a WD40 repeat protein, which binds and activates three important deubiquitinating enzymes (DUBs), USP1, USP12 and USP46
  • cell & other
    REGULATION
    Other is regulated by two WD40-repeat (WDR) proteins, WDR48/UAF1 and WDR20
