D3DR Inhibitors

Santa Cruz Biotechnology now offers a broad range of D3DR Inhibitors. D3DR proteins are members of the G protein coupled receptor family which are distinguished by their slow transmitting response to ligand binding. Dopamine receptors are divided into two classes, D1 (D1DR and D5DR) and D2 (D2DR, D3DR and D4DR), which differ in their functional characteristics, D1 receptors stimulate adenylyl cyclase while D2 receptors inhibit adenylyl cyclase activity. D3DR Inhibitors offered by Santa Cruz inhibit D3DR and, in some cases, other G protein coupled receptor and dopamine receptor related proteins.
