The Intracellular N-Terminal Domain of the Acid-Sensing Ion Channel 1a Participates in Channel Opening and Membrane Expression.

Abstract excerpt

Acid-sensing ion channels (ASICs) are widely expressed in the nervous system. The intracellular C terminus of ASIC1a has many sites involved in regulating its expression and the opening mechanism, but the role of the intracellular N-terminal domain is poorly understood. Here, we explored the correlation of ASIC1a intracellular N terminus with membrane expression and gate opening. We modified the N-terminal...
