Predicted to enable heparin binding activity; nerve growth factor binding activity; and serine-type endopeptidase activity. Acts upstream of or within determination of left/right symmetry; protein processing; and zygotic determination of anterior/posterior axis, embryo. Predicted to be active in several cellular components, including cell surface; collagen-containing extracellular matrix; and extracellular space. Is expressed in several structures, including alimentary system; early conceptus; genitourinary system; limb; and skeleton. Orthologous to human PCSK6 (proprotein convertase subtilisin/kexin type 6).
