Enables actin binding activity and metallocarboxypeptidase activity. Involved in proteolysis. Acts upstream of or within labyrinthine layer blood vessel development; positive regulation of angiogenesis; and syncytium formation by plasma membrane fusion. Predicted to be located in cytoskeleton and extracellular region. Predicted to be active in cytoplasm. Is expressed in brain and hippocampus. Orthologous to human VASH2 (vasohibin 2).
