The authors show that post-transcriptional regulation of the cilia-driven leftward flow target dand5 is central to symmetry breakage in frog, fish and mouse and is mediated by a 139 nt Bicc1 responsive element in the dand5 3′UTR, and they present evidence that Pkd2 regulates this Bicc1/dand5 module.
