TACR3

Receptor for the tachykinin neuromedin-K (neurokinin B), also able to bind and respond to tachynins substance K/neurokinin A and substance P. The rank order of affinity of this receptor to tachykinins is: neuromedin-K > substance K and substance P. Neuromedin-K binding to its receptor triggers G protein-coupled receptor signaling via activation of G(q) and phosphatidylinositol hydrolysis by phospholipase C. Neuromedin-K binding also triggers signaling via activation of adenylate cyclase activity which results in increased intracellular levels of cyclic AMP (cAMP) (By similarity)..
