additional information | concentration of progastrin in the antrum of PC1/3-null mice is elevated 3fold. Progastrin molecule is only partly cleaved at the dibasic Arg36-Arg37 site and even less at the Lys53-Lys54 site in the PC1/3-null mice | Mus musculus |

progastrin + H2O | PC1/3 initiates cleavage at the N-terminal di-arginine site (Arg36-Arg37) at an early stage in the processing. The endoproteolytic maturation of progastrin in normal G-cells appears to require an interplay, primarily between PC1/3 and PC2. Processing may begin with PC1/3, which is solely responsible for the cleavage of Arg36-Arg37. Subsequently, PC1/3 cleaves the crucial Arg73-Arg74. Later, in secretory granules, PC2 performs the partial cleavage of Lys53-Lys54 to ensure the production of gastrin-17 | Mus musculus | gastrin-34 + gastrin-17 | - |
