Description
Granzyme B, a 247 amino acid polypeptide, contains a leader sequence, which is cleaved by a signal peptidase and a two amino acid prodomain, which is cleaved by the lysosomal cysteine protease DPPI. The recombinant granzyme B is expressed in Pichia pastoris as the mature form and appears on SDS-PAGE as a triplet (~34, 32, and 30 kDa) due to three different glycosylations. Granzyme B, a serine protease, is the most prominent granzyme in a family of 11 found in the cytotoxic granules. The granzymes enter the target cell with the assistance of perforin, a critical molecule of the cytotoxic granules. In the target cell, the granzymes act on specific substrates involved with the cell death via apoptosis.
