ABSTRACT
<p><b>OBJECTIVE</b>To screen the protein interacting with retinoic acid receptor variant protein (RAR alpha-V) via the yeast two-hybrid technique (YTHT) and to find out the targets protein and study its biological function.</p><p><b>METHODS</b>The bait vector of pGBKT7-RAR alpha-V was constructed for screening proteins interacting with RAR alpha-V in K562 cell cDNA expression library via YTHT. The protein-protein interaction was confirmed with re-transformation in yeast and GST pull-down in vitro.</p><p><b>RESULTS</b>The bait vector was successfully constructed without toxicity, leakage and self-activation. Sixteen proteins were screened by YTHT and eight positive clones were identified by re-transformation in yeast. The interaction between RAR alpha-V and JTV-1 was confirmed by GST pull-down in vitro.</p><p><b>CONCLUSIONS</b>There are some kinds of proteins interacting with RAR alpha-V in cell. The biological dysfunction caused by certain protein-protein interaction may be involved in the pathogenesis of leukemia.</p>
