Enables endopeptidase activity. Involved in several processes, including circulatory system development; negative regulation of endothelial cell migration; and negative regulation of sprouting angiogenesis. Acts upstream of or within positive regulation of melanocyte differentiation; proteolysis; and response to bacterium. Located in cell surface and extracellular space. Is expressed in several structures, including alimentary system; cardiovascular system; embryo mesenchyme; eye; and genitourinary system. Orthologous to human ADAMTS9 (ADAM metallopeptidase with thrombospondin type 1 motif 9). [provided by Alliance of Genome Resources, Apr 2022]
