During embryonic development, DNA binding proteins help to specify and restrict the fates of pluripotent stem cells. In the developing kidney, Pax2 proteins are among the earliest markers for the renal epithelial cell lineage, with expression in the mesenchyme and in proliferating epithelia. The Pax2 protein is essential for interpreting inductive signals emanating from the ureter bud such that kidney mesenchyme can convert to epithelia. The biochemistry of Pax protein function is being studied in a variety of model systems. Through interactions with the adaptor PTIP, Pax proteins can recruit members of the Trithorax family of histone methyltransferases to imprint activating epigenetic marks on chromatin. However, the interactions with the co-repressor protein Grg4 can inhibit activation and instead recruit Polycomb repressor complexes to promote target gene silencing. We present a model whereby the regulated interactions of Pax proteins with available co-factors mediated activation or gene silencing at different stages of development. The implications for establishing and maintaining the epigenome are discussed.
