FoxD1 (BF-2) directly binds to a conserved HNF3β site in the Placental Growth Factor (PlGF) promoter and activates its transcription; PlGF is absent in BF-2 null kidney stroma, and exogenous PlGF stimulates ureteric bud branching in vitro, establishing PlGF as a direct, physiologically relevant transcriptional target of FoxD1 in renal stromal cells. |

The FOXD1 (FREAC-4) promoter is regulated by the transcription factor Ets-1; three Ets-1 cis-elements within the first 152 nucleotides upstream of the transcription start site mediate ~6-fold induction, and overexpression of Ets-1 in HEK293 cells is sufficient to increase FREAC-4 mRNA levels. |

FOXD1 activates the RI-alpha subunit of cAMP-dependent PKA via the 1b promoter in Sertoli cells through sequences downstream of the transcription start site; protein kinase B alpha/Akt1 strongly potentiates this effect, and an inactive FOXD1 mutant reduces cAMP-mediated induction of the RI-alpha 1b reporter, placing FOXD1 as an integrator of PKB and cAMP hormonal signals. |

Foxd1 is required in ventrotemporal (VT) retina for specification of the ipsilateral retinal projection: Foxd1-null mice lose Zic2 and EphB1 expression in VT retina, the Foxg1 domain expands, and VT RGC axons fail to be repulsed by chiasm cells in co-culture, aberrantly projecting contralaterally. Foxd1 also patterns the ventral diencephalon where the optic chiasm forms. |

Foxd1-null mice develop multiorgan systemic inflammation and exaggerated Th-cell cytokine production. |

In the developing chick retina, FoxD1 (CBF2) acts as a transcriptional repressor to establish temporal retinal identity: misexpression of FoxD1 represses FoxG1, GH6, SOHo1, and ephrin-A5, and induces EphA3. Chimeric mutant studies showed FoxD1 functions through its repressor domain. FGF and Wnt signaling induce region-specific FoxD1 expression in the optic vesicle. |

FOXD1 is transcriptionally regulated by canonical Sonic Hedgehog (Shh) signaling; Foxd1 is required downstream of Shh for the proliferative response — Foxd1 deletion abrogates SHH-induced proliferation, whereas FOXD1 overexpression alone is sufficient to induce proliferation. FOXD1 reduces reporter activity of a Fox enhancer in the second intron of Cdkn1c (p57), and Shh pathway activation of Foxd1 is followed by Cdkn1c downregulation, defining a Shh-Foxd1-Cdkn1c mitogenic circuit. |
