Predicted to enable receptor antagonist activity and transforming growth factor beta binding activity. Predicted to be involved in negative regulation of transforming growth factor beta receptor signaling pathway. Predicted to act upstream of or within several processes, including muscle cell development; negative regulation of DNA binding activity; and roof of mouth development. Predicted to be located in extracellular region. Orthologous to human WFIKKN1 (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 1).
