CC -!- FUNCTION: Involved in the processing of hormone and other protein
CC precursors at sites comprised of pairs of basic amino acid residues.
CC Responsible for the release of glucagon from proglucagon in pancreatic
CC A cells (By similarity). {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}.
