Briefly, the preproglucagon gene undergoes tissue-specific post-translational modification with the help of specific propeptidase convertase (PC1/3) to produce two variants of GLP-1, the amidated GLP-1 [736], and the glycine-extended GLP-1 [737] in the ileum and hypothalamus ( FIGURE 1 Notably, the insulinotropic actions of circulating GLP-1 are facilitated through a two-domain binding interaction with GLP-1R (Figure 2), a structurally well-characterized prototypical class B GPCR, which recruits the G s -subunit of the heterotrimeric G-protein for cAMP-mediated downstream signaling, involving protein kinase A (PKA) and exchange protein activated by cAMP (EPAC), leading to insulin exocytosis
