Summary: Enables several functions, including identical protein binding activity; monoatomic ion channel activity; and transmembrane transporter binding activity. Contributes to monoatomic cation channel activity and sour taste receptor activity. Involved in several processes, including cellular response to acidic pH; detection of chemical stimulus involved in sensory perception of sour taste; and protein tetramerization. Located in endoplasmic reticulum and plasma membrane. Part of calcium channel complex and receptor complex. Colocalizes with cell surface. Is expressed in cochlea; medulla oblongata; spinal cord; and tongue. Orthologous to human PKD2L1 (polycystin 2 like 1, transient receptor potential cation channel).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
