Notes: Spadin is an inhibitor of the two-pore domain potassium channel K2P2.1/TREK1 (Ki = 10 nM in homogenates from COS-7 cells expressing K2P2.1/TREK1) that corresponds to amino acids 12-28 of human sortilin, also known as the neurotensin-3 receptor (NTS3).{64566} It also binds to sortilin in C13NJ microglial cells (Ki = 8 nM). Spadin inhibits currents induced by arachidonic acid (Item Nos. 90010 / 90010.1 / 10006607) in COS-7 cells expressing K2P2.1/TREK1 (IC50 = 70.7 nM). It decreases immobility time in the forced swim test in mice.
