Predicted to enable metalloendopeptidase inhibitor activity and protease binding activity. Acts upstream of or within Notch signaling pathway. Predicted to be located in sarcomere. Predicted to be active in extracellular matrix and extracellular space. Is expressed in several structures, including brain ventricular layer; heart; ovary; skin; and ventral grey horn. Human ortholog(s) of this gene implicated in nephroblastoma. Orthologous to human TIMP4 (TIMP metallopeptidase inhibitor 4). [provided by Alliance of Genome Resources, Apr 2022]
