Glu-Arg is a dipeptide linked by L-glutamic acid and L-arginine. Glu-Arg contributes to the construction of the hydrophobic network and maintenance of stability of mouse cAMP-dependent protein kinase; it acts as a core hub connecting the activation segment and the GHI subdomain in eukaryotic protein kinases, and promotes signal transmission between elements and within enzymes. As a salt bridge, Glu-Arg regulates the formation and unfolding rates of α-helices, and its optimized spatial conformation is conducive to the stability and folding rate of α-helices. Glu-Arg induces concentration-dependent intracellular calcium changes in cultured human fungiform taste bud cells .
