Predicted to enable transforming growth factor beta binding activity. Predicted to be involved in negative regulation of epithelial to mesenchymal transition and negative regulation of transforming growth factor beta receptor signaling pathway. Predicted to act upstream of or within cellular response to hypoxia and cellular response to redox state. Predicted to be located in cell surface; extracellular exosome; and mitochondrion. Predicted to be active in extracellular matrix; extracellular space; and plasma membrane. Orthologous to human VASN (vasorin). [provided by Alliance of Genome Resources, Apr 2022]
