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 negative regulation of DNA binding activity; roof of mouth development; and transforming growth factor beta receptor signaling pathway. Predicted to be located in extracellular space. Orthologous to human WFIKKN2 (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 2).
