ASIC1 is a member of a family of Na+ channels that are activated by external protons. The family includes four additional members: ASIC2, ASIC3, ASIC4 and ASIC5. The ASICs are in fact part of a larger superfamily named degenerin/epithelial Na+ channels (DEG/ENaC) and share with it the same basic characteristics: two transmembrane spanning domains, a large extracellular domain and short intracellular N- and C-termini.
There are two recognized splice variants of the ASIC1 gene that differ on their N-termini, ASIC1a and ASIC1b that have different tissue distributions and functions.
ASIC1 responds to a decrease in extracellular pH with an inward cation current that is quickly inactivated despite the continuous presence of protons in the medium.
Recently, ASIC1 has been implicated in cognitive processes such as learning and memory.

Expression of ASIC1 in rat medulla.Immunohistochemical staining of rat brain sections using Anti-ASIC1 Antibody (#ASC-014). ASIC1 staining in the medulla is detected in the ventrolateral medulla (VLM), (left panel) and in the dorsal medulla (DM), (middle panel). Antibody specificity was demonstrated by preincubating the antibody with the control antigen (right panel).Adapted from Song, N. et al. (2016) Sci. Rep. 6, 38777. with permission of SPRINGER NATURE.
