To define the mechanism underlying signal transducer and activator of transcription (STAT) protein recruitment to the interleukin 10 ( IL-10 ) receptor , the STAT proteins activated by IL-10 in different cell populations were first defined using electrophoretic mobility shift assays .
 ( protein: signal transducer and activator of transcription (STAT) protein, None) , ( protein: IL-10, None) , ( protein: interleukin 10, None) , ( protein: interleukin 10 ( IL-10 ) receptor, None) , ( protein: IL-10, None) , ( protein: STAT proteins, None)
