Predicted to enable serine-type endopeptidase inhibitor activity. Involved in negative regulation of angiogenesis. Acts upstream of or within negative regulation of epithelial cell proliferation involved in prostate gland development. Located in extracellular space. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and sensory organ. Used to study osteogenesis imperfecta type 6. Human ortholog(s) of this gene implicated in several diseases, including brain edema; eye disease (multiple); leukostasis; non-alcoholic steatohepatitis; and osteogenesis imperfecta type 6. Orthologous to human SERPINF1 (serpin family F member 1). [provided by Alliance of Genome Resources, Apr 2022]
