Function |
Cation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Also permeable for Li(+) and K(+). Generates a biphasic current with a fast inactivating and a slow sustained phase. Heteromeric channel assembly seems to modulate. {ECO:0000269|PubMed:14762118}.
|
Subcellular Location |
Cell membrane {ECO:0000269|PubMed:15537887, ECO:0000269|PubMed:15708491}; Multi-pass membrane protein {ECO:0000269|PubMed:15537887, ECO:0000269|PubMed:15708491}. Note=Localized at the plasma membrane, in the soma and punctated peripheral processes of neurons.
|
Tissue Specificity |
Expressed by sensory neurons. Expressed by nociceptive sensory neurons, spiral ganglion (SG) neurons and the retina (at protein level). Isoform 1 and isoform 2 are expressed in outer nuclear layer of retina (photoreceptors) and to a lower extent in distal and proximal inner nuclear layer. {ECO:0000269|PubMed:14762118, ECO:0000269|PubMed:15537887}.
