Disease relevance of WWP1

 

High impact information on WWP1

 

Biological context of WWP1

 

Anatomical context of WWP1

  • Finally, WWP1 was amplified and overexpressed in some cancer cell lines from the prostate and breast, which negatively regulated the function of KLF5 in gene regulation [5].
  • Coexpression of human Notch1 (hN1) depleted WWP1 from the nucleus to colocalise with hN1 in early endosomes, dependent on the presence of the C-terminal HECT domain [9].
  • As expected, WWP1 was expressed, like ENaC, in the bronchiolar epithelium [10].
 

Physical interactions of WWP1

  • Furthermore we found that full-length expressed WWP1 could interact in vitro with the cytoplasmic domain of human Notch1 [9].
  • Here, we demonstrate that WWP1 interacts with KLF2 in vivo and mediates both poly-ubiquitination and proteasomal degradation of KLF2 [11].
 

Enzymatic interactions of WWP1

  • However, unlike Smurfs, WWP1 failed to ubiquitinate R-Smads and SnoN [12].
 

Regulatory relationships of WWP1

  • Using a TGF-beta-responsive reporter in mammalian cells, we found that WWP1 inhibited transcriptional activities induced by TGF-beta [12].
  • Our experiments demonstrate for the first time that WWP1 promotes ubiquitination and degradation of KLF2 and is not involved in the ubiquitin-transfer reaction [11].
