title: JAK/STAT signalling: STAT cannot play with Ken and Barbie.
abstract: Transcriptional responses to the activation of a signalling pathway are cell-specific. New data show that the sequence-specific transcriptional repressors of the KEN/BCL-6 family play an important role in the selection of STAT targets in vertebrates and invertebrates, indicating that all STAT proteins may share this ancestral mechanism.
