Abstract:Phospholipid-protein interaction is highly specialized at the membranous nanodomains and critical for membrane receptor signaling. Calcium-permeable acid-sensing ion channel isoform 1a (ASIC1a) is a major neuronal proton sensor that contributes to synaptic plasticity. The functional outcome of ASIC1a is dependent on its surface targeting in synaptic subdomains; however, the lipid environment for ASIC1a and its role in channel targeting remain poorly understood. Here, we report that anionic phosphatidylserine (… Show more
