bmp1 and mini fin are functionally redundant in regulating formation of the zebrafish dorsoventral axis
Drosophila metalloproteinase Tolloid (TLD) is responsible for cleaving the antagonist Short gastrulation (SOG), thereby regulating signaling by the bone morphogenetic protein (BMP) Decapentaplegic (DPP). In mice there are four TLD-related proteinases, two of which, BMP1 and mammalian Tolloid-like 1 (mTLL1), are responsible for cleaving the SOG orthologue Chordin, thereby regulating signaling by...
متن کاملA novel chordin-like
Bone morphogenetic proteins (BMPs) belong to the transforming growth factor (TGF) β super family. These molecules play important roles during many organogenic processes, even though they were originally identified as factors promoting the ectopic formation of cartilage and bone. The concentration of active BMP is controlled in part by inhibitors from three BMP binding protein families: short ga...
متن کاملDorsoventral Patterning in Xenopus: Inhibition of Ventral Signals by Direct Binding of Chordin to BMP-4
Chordin (Chd) is an abundant protein secreted by Spemann organizer tissue during gastrulation. Chd antagonizes signaling by mature bone morphogenetic proteins (BMPs) by blocking binding to their receptors. Recombinant Xenopus Chd binds to BMP-4 with high affinity (KD, 3 x 10(-10) M), binding specifically to BMPs but not to activin or TGF-beta1. Chd protein is able to dorsalize mesoderm and to n...
متن کاملThe Chordin Morphogenetic Pathway.
The ancestral Chordin/bone morphogenetic protein (BMP) signaling pathway that establishes dorsal-ventral (D-V) patterning in animal development is one of the best understood morphogenetic gradients, and is established by multiple proteins that interact with each other in the extracellular space-including several BMPs, Chordin, Tolloid, Ont-1, Crossveinless-2, and Sizzled. The D-V gradient is ad...
متن کاملShort- and long-range functions of Goosecoid in zebrafish axis formation are independent of Chordin, Noggin 1 and Follistatin-like 1b.
The organizer is essential for dorsal-ventral (DV) patterning in vertebrates. Goosecoid (Gsc), a transcriptional repressor found in the organizer, elicits partial secondary axes when expressed ventrally in Xenopus, similar to an organizer transplant. Although gsc is expressed in all vertebrate organizers examined, knockout studies in mouse suggested that it is not required for DV patterning. Mo...
