| Outline of Final Research Achievements |
The acid-sensing ion channel (ASIC) family is a major branch of the mechanosensory degenerin/epithelial Na+ channel superfamily. Here, we report that acid-sensing ion channels (ASICs) type 1a knockout (KO) female mice exhibit the impairment in maternal behavior. The ASIC 1a KO female mice also show the downregulation of the dopamine transporter (DAT). While the function of these interactions is not well understood, it might be possible that the interactions between coexisting plural channels and transporters play some crucial roles to maintain the synaptic action. In this paper, we propose that the ASIC 1a KO female mice express the impairment in maternal behavior from the downregulation of the DAT.
