title: [Isolation of Id1 interaction protein in human prostate cancer].
abstract: OBJECTIVE
  To isolate the inhibitor of DNA binding 1 (Id1) interaction protein and to determine the role and action mechanism of Id1 in human prostate cancer.
  
  
  METHODS
  The expression vector pET-28a/Id1 was established and used as a bait to prey the interaction protein by pull-down assay.
  
  
  RESULTS
  A clear interaction protein band was observed by SDS-PAGE, which was found to be activating transcription factor 3 (ATF3) by Western blotting.
  
  
  CONCLUSIONS
  Id1 may play a role in human prostate cancer by interacting with ATF3.
