Predicted to enable metalloendopeptidase inhibitor activity and protease binding activity. Involved in negative regulation of metalloendopeptidase activity. Acts upstream of or within cellular response to organic substance. Located in basement membrane. Is expressed in several structures, including alimentary system; central nervous system; eye posterior segment; genitourinary system; and musculoskeletal system. Used to study Sorsby's fundus dystrophy and dilated cardiomyopathy. Human ortholog(s) of this gene implicated in Sorsby's fundus dystrophy; breast carcinoma; and urinary bladder cancer. Orthologous to human TIMP3 (TIMP metallopeptidase inhibitor 3). [provided by Alliance of Genome Resources, Apr 2022]
