WDR20 Regulates Activity of USP12 x UAF1 Deubiquitinating Enzyme Complex

Scientists at Dana-Farber Cancer Institute have uncovered new insights into the regulation of the USP12 x UAF1 deubiquitinating enzyme complex. The USP12 x UAF1 complex plays a crucial role in various cellular processes, including DNA repair and cell cycle regulation. A study published in the Journal of Biological Chemistry has revealed that WDR20, a WD40-repeat containing protein, binds and stimulates the enzymatic activity of the USP12 x UAF1 complex. Furthermore, the researchers demonstrated the purification of a ternary USP12 x UAF1 x WDR20 complex and showed that WDR20 does not affect the FA pathway or DNA damage responses.

Key Takeaways:

  • WDR20 binds and stimulates the enzymatic activity of the USP12 x UAF1 complex.
  • The USP12 x UAF1 x WDR20 complex is a ternary complex with WDR20 acting as a stimulatory subunit.
  • WDR20 does not affect the FA pathway or DNA damage responses.
