Acid-sensing ion channel 3 (ASIC3) also known as amiloride-sensitive cation channel 3 (ACCN3) or testis sodium channel 1 (TNaC1) is a protein that in humans is encoded by the ASIC3 gene. The ASIC3 gene is one of the five paralogous genes that encode proteins that form trimeric acid-sensing ion channels (ASICs) in mammals.[5] The cDNA of this gene was first cloned in 1998.[6][7] The ASIC genes have splicing variants that encode different proteins that are called isoforms.
These genes are mainly expressed in the central and peripheral nervous system.
ASICs can form both homotrimeric (meaning composed of three identical subunits) and heterotrimeric channels.[8]
Structure and function
This gene encodes a member of the ASIC/ENaC superfamily of proteins.[9] The members of this family are amiloride-sensitive sodium channels that contain intracellular N and C termini, 2 hydrophobic transmembrane (TM) regions, and a large extracellular loop, which has many cysteine residues with conserved spacing. The TM regions are generally symbolized as TM1 (clone to N-terminus) and TM2 (close to C-terminus).
The pore of the channel through which ions selectively flow from the extracellular side into the cytoplasm is formed by the three TM2 regions of the trimer.[5]
Interactions
ASIC3 has been shown to interact with LIN7B,[10] GOPC[10] and MAGI1.[10]
