Because these are the characteristics of a signal transducer and activator of transcription (Stat) protein , we determined whether antibodies to Stat proteins will interfere with gel mobility shift and found that antibodies to IL-4 Stat , also known as Stat6 , but not antibodies to other Stat proteins , interfere with the formation of the IL-4 NAF complex .
 ( protein: IL-4, None) , ( protein: Stat6, None) , ( protein: Stat proteins, None) , ( protein: antibodies to Stat proteins, None) , ( protein: IL-4 Stat, None) , ( protein: antibodies, None) , ( protein: IL-4, None) , ( protein: antibodies to IL-4 Stat, None) , ( protein: IL-4 NAF complex, None) , ( protein: signal transducer and activator of transcription (Stat) protein, None)
