We demonstrated that ZFPIP is expressed in embryonic female genital tract but also in other PBX1 expression domains such as the developing head and the limb buds. We further showed that ZFPIP is able to bind physically and in vivo to PBX1 and moreover, that it prevents the binding of HOXA9/PBX complexes to their consensus DNA site. We suggest that ZFPIP is a new type of PBX1 partner that could participate in PBX1 function during several developmental pathways. |

the ability of HoxB8 to heterodimerizes with endogenous Pbx proteins on DNA alters gene transcription in a manner that prevents progression through an intrinsic genetic differentiation program. In conjunction with Pbx, HoxB8 could alter transcription of Pbx target genes by direct or indirect mechanisms. |

We show that the Pbx1 and Meis2 homeodomain proteins interact with Klf4 and can be recruited to DNA elements comprising a Klf4 site or G C box, with adjacent Meis and Pbx sites. Meis2d and Pbx1a activate expression of p15(Ink4a) and E-cadherin, dependent on the Meis2d transcriptional activation domain. We suggest a model in which genes with Klf4 sites can be cooperatively activated by Meis2/Pbx1 and Klf4, dependent primarily on recruitment by Klf4. |

we show that Pbx proteins exist as stable heterodimers with a novel homeodomain protein, Prep1. Here we show that Prep1-Pbx interaction presents novel structural features: it is independent of DNA binding and of the integrity of their respective homeodomains, and requires sequences in the N-terminal portions of both proteins. The Prep1-Pbx protein-protein interaction is essential for DNA-binding activity. |

This protein that we have termed hematopoietic PBX-interacting protein (HPIP) is mainly localized in the cytosol and in small amounts in the nucleus. The region of PBX that interacts with HPIP includes both the homeodomain and immediate N-terminal flanking sequences. Strikingly, electrophoretic mobility shift assays revealed that HPIP inhibits the ability of PBX-HOX heterodimers to bind to target sequences. |

Our results in ES cells suggest that Engrailed inhibits Fgf8 expression in the absence of Pbx1. We identified single Engrailed- and Pbx-binding sites in the Fgf8 intron that inhibit expression of Fgf8 in mouse ES cells, but that together can allow full Fgf8 expression. Our data support the model that Engrailed heterodimerized with Pbx might activate transcription, while Engrailed or Pbx proteins alone might repress transcription |
