    Kinin and its receptor are an important part of the kallikrein-kinin system (KKS)


    Although the amino acid sequence of each active kinin in the KKS system is similar, different kinins have obvious selectivity for B1R and B2R

    In this study, the researchers used cryo-electron microscopy to analyze the three-dimensional structure of B1R and B2R combined with Des-Arg 10- kallidin and bradykinin and downstream Gq protein complexes, with a resolution of 3.
