Description

Predicted to have several functions, including calcium ion binding activity; cation channel activity; and muscle alpha-actinin binding activity. Involved in several processes, including Kupffer's vesicle development; circulatory system development; and kidney development. Localizes to basolateral plasma membrane; cilium; and endoplasmic reticulum. Used to study autosomal dominant polycystic kidney disease. 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. Is expressed in several structures, including germ ring; heart; nervous system; pleuroperitoneal region; and tail bud. Orthologous to human PKD2 (polycystin 2, transient receptor potential cation channel).
