Predicted to enable several functions, including Wnt-activated receptor activity; protein kinase binding activity; and transmembrane transporter binding activity. Predicted to contribute to calcium channel activity. Involved in positive regulation of cytosolic calcium ion concentration. Located in Golgi apparatus and lateral plasma membrane. Used to study polycystic kidney disease. Human ortholog(s) of this gene implicated in autosomal dominant polycystic kidney disease; intracranial aneurysm; and polycystic kidney disease 1. Orthologous to human PKD1 (polycystin 1, transient receptor potential channel interacting). [provided by Alliance of Genome Resources, Apr 2022]
