Predicted to enable endopeptidase inhibitor activity and protease binding activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to be located in extracellular space. Human ortholog(s) of this gene implicated in anterior segment dysgenesis 8 and otitis media. Orthologous to several human genes including A2ML1 (alpha-2-macroglobulin like 1). [provided by Alliance of Genome Resources, Apr 2022]
