General annotation (Comments)
| Function | Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Responsible for the release of glucagon from proglucagon in pancreatic A cells. Ref.8 |
| Catalytic activity | Release of protein hormones and neuropeptides from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds. |
| Subcellular location | Cytoplasmic vesicle › secretory vesicle. Note: Localized in the secretion granules. |
| Sequence similarities | Belongs to the peptidase S8 family. Furin subfamily. |
| Sequence caution | The sequence CAA21069.2 differs from that shown. Reason: Erroneous initiation. The sequence CAB89428.2 differs from that shown. Reason: Erroneous initiation. The sequence CAB96732.2 differs from that shown. Reason: Erroneous initiation. |
