Auto-inhibition in a Transcription Factor: An Interview with JBC Author Peter JohnsonJuly 1, 2010--In this podcast, JBC Associate Editor Joan Conaway of the Stowers Institute interviews Paper of the Week author Peter Johnson from the National Cancer Institute about his research on CEPB-β. In his recent JBC paper "CCAAT/enhancer binding protein β DNA binding is auto-inhibited by multiple elements that also mediate association with p300/CBP," he describes this transcription factor's novel auto-inhibitory mechanism and its dual role in oncogenesis and cell senescence. The pair first talk about CEPB-β's normal physiological roles and its interactions with oncogenic ras, a series of techniques used to identify the important regulatory domains and conformational changes that correspond with the activation of this normally inert protein. The interview wraps up with how Johnson's findings might be translated to other important transcription factors and cancer research in general.
