CC   -!- FUNCTION: Serine endopeptidase which is involved in the processing of
CC       hormone and other protein precursors at sites comprised of pairs of
CC       basic amino acid residues. Responsible for the release of glucagon from
CC       proglucagon in pancreatic A cells (By similarity).
CC       {ECO:0000250|UniProtKB:P16519}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of protein hormones and neuropeptides from their
CC         precursors, generally by hydrolysis of -Lys-Arg-|- bonds.;
CC         EC=3.4.21.94;
CC   -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle
CC       {ECO:0000250|UniProtKB:P16519}. Secreted
CC       {ECO:0000250|UniProtKB:P16519}. Note=Localized in the secretion
CC       granules. {ECO:0000250|UniProtKB:P16519}.
CC   -!- SIMILARITY: Belongs to the peptidase S8 family. Furin subfamily.
CC       {ECO:0000305}.
