Using a fragment of K protein as bait in the yeast two-hybrid screen , we isolated a cDNA that encodes a protein whose primary structure has extensive similarity to the Drosophila melanogaster extra sex combs (esc) gene product , Esc , a putative silencer of homeotic genes .
 ( DNA: homeotic genes, None) , ( protein: Drosophila melanogaster extra sex combs (esc) gene product, None) , ( DNA: cDNA, None) , ( protein: Esc, None) , ( protein: K protein, None)
