Enables calcium ion binding activity; metallopeptidase activity; and zinc ion binding activity. Involved in several processes, including positive regulation of neuroinflammatory response; positive regulation of nitric oxide biosynthetic process; and positive regulation of tumor necrosis factor production. Located in extracellular space. Biomarker of congestive heart failure. Human ortholog(s) of this gene implicated in breast cancer and carotid artery disease. Orthologous to human MMP8 (matrix metallopeptidase 8). [provided by Alliance of Genome Resources, Apr 2022]
