We have determined how the phosphorylation of the retinoblastoma family ( pRb , p107 , and p130 ) is governed in individual cell cycle phases of Daudi B-cells during cell cycle exit triggered by alpha-interferon ( alpha-IFN ).
 ( protein: retinoblastoma family, None) , ( protein: alpha-IFN, None) , ( cell line: Daudi B-cells, None) , ( protein: p130, None) , ( protein: alpha-interferon, None) , ( protein: pRb, None) , ( protein: p107, None)
