Summary: Enables muscle alpha-actinin binding activity. Involved in positive regulation of cytosolic calcium ion concentration. Predicted to be located in several cellular components, including basal cortex; endoplasmic reticulum membrane; and microtubule cytoskeleton. Predicted to be part of cation channel complex and polycystin complex. Predicted to be active in membrane. Biomarker of acute kidney failure. 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.
