Summary: Enables several functions, including ATPase binding activity; identical protein binding activity; and monoatomic cation channel activity. Involved in several processes, including detection of nodal flow; monoatomic cation transmembrane transport; and positive regulation of biosynthetic process. Acts upstream of or within several processes, including intracellular calcium ion homeostasis; liver development; and negative regulation of ryanodine-sensitive calcium-release channel activity. Located in several cellular components, including basal cortex; ciliary membrane; and microtubule cytoskeleton. Part of polycystin complex. Colocalizes with cell-cell junction. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Used to study autosomal dominant polycystic kidney disease and polycystic kidney disease 2. Human ortholog(s) of this gene implicated in autosomal dominant polycystic kidney disease; intracranial aneurysm; polycystic kidney disease; polycystic kidney disease 2; and retinal degeneration. Orthologous to human PKD2 (polycystin 2, transient receptor potential cation channel). [provided by Alliance of Genome Resources, Dec 2024]

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.
