The intensity of the BMP signal is determined by cell surface receptors that phosphorylate Smad1/5/8 at the C-terminus. axes. The positional information produced by these signal gradients are seamlessly integrated in each individual embryo. A classic example of the self-regulating nature of this patterning integration is demonstrated by cutting a Vamp5 blastula stage embryo in… Continue reading The intensity of the BMP signal is determined by cell surface
