Testis sodium channel 1
FunctionCation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Generates a biphasic current with a fast inactivating and a slow sustained phase. In sensory neurons is proposed to mediate the pain induced by acidosis that occurs in ischemic, damaged or inflamed tissue. May be involved in hyperalgesia. May play a role in mechanoreception. Heteromeric channel assembly seems to modulate channel properties.
Tissue specificityExpressed by sensory neurons. Strongly expressed in brain, spinal chord, lung, lymph nodes, kidney, pituitary, heart and testis.
Sequence similaritiesBelongs to the amiloride-sensitive sodium channel (TC 1.A.6) family. ACCN3 subfamily.
Developmental stageExpressed in fetal tissues, expression increases in lung and kidney adult tissues.
DomainThe PDZ domain-binding motif is involved in interaction with LIN7A, GOPC and MAGI1.
Post-translational modificationsPhosphorylated by PKA. Phosphorylated by PKC. In vitro, PRKCABP/PICK-1 is necessary for PKC phosphorylation and activation of a ACCN3/ASIC3-ACCN1/ASIC2b channel, but does not activate a homomeric ACCN3 channel.
Cellular localizationCell membrane. Cytoplasm. Cell surface expression may be stabilized by interaction with LIN7B and cytoplasmic retention by interaction with DLG4. In part cytoplasmic in cochlea cells.
