Abstract:
A wave of biochemical and genetic progress has identified proteins that influence transcription by modifying chromatin. Many such factors are broadly conserved and, strikingly, occur in human diseases as partners in chromosomal translocations. Understanding the function of these factors will be key to defining mechanisms of transcriptional regulation and understanding cancers linked to aberrant chromatin modification.
