Bone Morphogenetic Protein-13 （BMP-13）, known as Growth differentiation factor 6 （GDF6）, is an extracellular multifunctional cytokine that is also a member of the TGFβ family. BMP-13 can bind with the TGFβ receptor and induce SMAD protein signal transduction. BMP-13 is a regulatory protein that can affect the growth and differentiation of developing embryos. Moreover, it plays a role in regulating the patterning of the ectoderm and controlling eye development.
