Bone Morphogenetic Protein (Bmp) signalling has a critical function in patterning vertebrate and invertebrate embryos. A key regulator of Bmp signalling is Chordin, which binds Bmps and prevents them from interacting with their receptors. Two new papers identify the Frizzled-related protein Sizzled as an unexpected regulator of Chordin stability.
