Predicted to enable BMP binding activity and BMP receptor activity. Predicted to be involved in negative regulation of determination of dorsal identity; negative regulation of myoblast differentiation; and negative regulation of signal transduction. Predicted to act upstream of or within several processes, including animal organ development; negative regulation of canonical Wnt signaling pathway; and negative regulation of cell fate commitment. Predicted to be active in extracellular space. Orthologous to human SOSTDC1 (sclerostin domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
