Regulation of neural crest development by the formin family protein Daam1.

ABSTRACT: The neural crest (NC) multipotent progenitor cells form at the neural plate border and migrate to diverse locations in the embryo to differentiate into many cell types. NC is specified by several embryonic pathways, however the role of noncanonical Wnt signaling in this process remains poorly defined. Daam1 is a formin family protein that is present in embryonic ectoderm at the time of NC formation and can mediate noncanonical Wnt signaling. Our interference experiments indicated that Daam1 is required for NC gene activation. To further study the function of Daam1 in NC development we used a transgenic reporter Xenopus line, in which GFP transcription is driven by sox10 upstream regulatory sequences. The activation of the sox10:GFP reporter in a subset of NC cells was suppressed after Daam
