Predicted to enable serine-type endopeptidase inhibitor activity. Involved in cellular response to interleukin-1; cellular response to lipopolysaccharide; and response to estradiol. Located in extracellular space. Biomarker of atrial fibrillation; disseminated intravascular coagulation; myocardial infarction; and osteonecrosis. Human ortholog(s) of this gene implicated in several diseases, including factor VIII deficiency; osteonecrosis; thrombophilia (multiple); toxic shock syndrome; and transient cerebral ischemia. Orthologous to human TFPI (tissue factor pathway inhibitor). [provided by Alliance of Genome Resources, Apr 2022]
