FOXD3 is a transcription factor with a role in specifying cell fates in the neural crest (reviewed in Mort et al, 2015; Golson and Kaestner, 2016; Goding and Arnheiter, 2019). In a bipotent precursor that can give rise to both glial and melanocyte cell lineages, FOXD3 represses expression of microphthalmia-associated transcription factor (MITF), itself a key regulator of melanocyte cell fate (reviewed in Goding and Arnheiter, 2019).
FOXD3 contains DNA-binding motifs and can act as either a transcriptional activator or a transcriptional repressor in different contexts by direct binding to a cognate DNA element 5'-A[AT]T[AG]TTTGTTT-3' (Guo et al, 2002; reviewed in Mort et al, 2015). Consistent with this, in zebrafish models, FOXD3 has been demonstrated to bind directly to the promoter of the equivalent of MITF-M (in zebrafish called mitfa) and repress expression in the bipotent precursor and non-melanocytic lineages (Curran et al, 2009, Curran et al, 2010).
In contrast, direct binding of FOXD3 was not observed by electrophoretic mobility shift assays using nuclear extracts from B16-F10 mouse melanoma cells. Instead, in this system, FOXD3 appears to repress MITF gene expression by directly binding to the MITF-transcriptional activator PAX3 and inhibiting its interaction with PAX3 sites in the MITF-M promoter. Consistent with this, chicken GST-FOXD3 interacts directly with PAX3 as assessed with a pulldown assay with B16-F10 nuclear extract (Thomas and Erickson, 2009).
