Acid-sensing ion channels (ASICs) are proton-gated cation channels that are
widely expressed in both the peripheral and central nervous systems. ASICs
contribute to a variety of pathophysiological conditions that involve tissue
acidosis, such as ischemic stroke, epileptic seizures and multiple sclerosis.
Although much progress has been made in researching the structure-function
relationship and pharmacology of ASICs, little is known about the trafficking of
ASICs and its contribution to ASIC function. The recent identification of the
mechanism of membrane insertion and endocytosis of ASIC1a highlights the emerging
role of ASIC trafficking in regulating its pathophysiological functions. In this
review, we summarize the recent advances and discuss future directions on this
topic.
