Summary
Predicted to enable serine-type endopeptidase inhibitor activity. Involved in sexual reproduction. Located in extracellular space. Is expressed in adult head. Human ortholog(s) of this gene implicated in antithrombin III deficiency; disseminated intravascular coagulation; intermediate coronary syndrome; thrombosis; and toxic shock syndrome. Orthologous to several human genes including SERPINB1 (serpin family B member 1); SERPINB12 (serpin family B member 12); and SERPINB13 (serpin family B member 13).
