Isolation of Id1 interaction protein in human prostate cancer / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>The expression vector pET-28a/Id1 was established and used as a bait to prey the interaction protein by pull-down assay.</p><p><b>RESULTS</b>A clear interaction protein band was observed by SDS-PAGE, which was found to be activating transcription factor 3 (ATF3) by Western blotting.</p><p><b>CONCLUSION</b>Id1 may play a role in human prostate cancer by interacting with ATF3.</p>
