Predicted to enable several functions, including lipoprotein particle binding activity; lipoprotein particle receptor binding activity; and serine-type endopeptidase activity. Involved in several processes, including cellular response to insulin stimulus; cholesterol homeostasis; and protein autoprocessing. Located in extracellular space and rough endoplasmic reticulum. Human ortholog(s) of this gene implicated in familial hypercholesterolemia and hypobetalipoproteinemia. Orthologous to human PCSK9 (proprotein convertase subtilisin/kexin type 9).
