Bradykinin receptors are "cell surface receptors that bind bradykinin and related kinins with high affinity and trigger intracellular changes which influence the behavior of cells. The identified receptor types (B-1 and B-2, or BK-1 and BK-2) recognize endogenous kallidin; t-kinins; and certain bradykinin fragments as well as bradykinin itself."[1]

Bradykinin receptors are G-Protein-coupled cell surface receptors.

Classification

Bradykinin B1 receptor

"A subtype of bradykinin receptor that is induced in response to inflammation. It may play a role in chronic inflammation and has a high specificity for kinins lacking the C-terminal arginine such as des-Arg(10)-kallidin and des-Arg(9)-bradykinin. The receptor is coupled to G-Protein, GQ-G11 alpha family and G-Protein, GI-GO alpha family signaling proteins."[2]

Bradykinin B2 receptor

"A constitutively expressed subtype of bradykinin receptor that may play a role in the acute phase of the inflammatory and pain response. It has high specificity for intact forms of bradykinin and kallidin. The receptor is coupled to G-Protein, GQ-G11 alpha family and G-Protein, GI-GO alpha family signaling proteins."[3]
