“…More recently in mouse kidney development, Cerberus has been shown to regulate the spatial organization within the ureteric tree, at least in part by antagonizing BMP-2 and -4 activity (Chi et al, 2011). In the chick embryo, Cerberus interacts with Nodal during left-right axis determination through complex interactions which appear to involve not only the induction of expression of Cerberus by Nodal on the left-side of the mesoderm (Tavares, Andrade, Silva, & Belo, 2007) but also the functioning of Cerberus in this process as a BMP coagonist rather than antagonist (Yu et al, 2008). Birds express Caronte, a close homologue of Cerberus which is also involved in left-right asymmetrical morphogenesis (Yokouchi, Vogan, Pearse, & Tabin, 1999).…”
