Target Background

Receptor for bradykinin. It is associated with G proteins that activate a phosphatidylinositol-calcium second messenger system.
Gene References into Functions
  1. Study results indicated that the bradykinin B2 receptor-mediated pathway is involved in the cPLA2-related inflammatory response from the PKC pathway in traumatic brain injury. PMID: 29894755
  2. The most characteristic signaling pathways for B2R and D2R, dependent on intracellular Ca(2+) and cAMP concentration, respectively, were analyzed in cells presenting similar endogenous expression of B2R and D2R.The evidence of B2R-D2R dimerization may open new perspectives in the modulation of diverse cellular functions which depend on their activation.
