Identification of the Ca2+ Blocking Site of Acid-sensing Ion Channel (ASIC) 1: Implications for Channel Gating

Acid-sensing ion channels ASIC1a and ASIC1b are ligand-gated ion channels that are activated by H+ in the physiological range of pH. The apparent affinity for H+ of ASIC1a and 1b is modulated by extracellular Ca2+ through a competition between Ca2+ and H+. Here we show that, in addition to modulatin...
