Family
Peptidase S1 family, Kallikrein subfamily
Subcellular location
Secreted; Golgi apparatus
Function
Possible multifunctional protease. Efficiently cleaves 'bz-Phe-Arg-4-methylcoumaryl-7-amide', a kallikrein substrate, and weakly cleaves other substrates for kallikrein and trypsin. Cleaves synthetic peptides after arginine but not lysine residues.
