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 By similarity.

Catalytic activity

Release of protein hormones and neuropeptides from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds.

Subcellular location

Cytoplasmic vesiclesecretory vesicle. Note: Localized in the secretion granules.

Sequence similarities

Belongs to the peptidase S8 family. Furin subfamily.
